Outline

Mass is the most important characteristic for understanding particle mechanics. Many billions of dollars and thousands of physicist-lives have been spent measuring mass because it is such an essential concept in Newtonian mechanics. This applies to particles large and small, from planets to electrons. But the richest trove of precise, reproducible data comes from nuclear particles. Mass is their most salient characteristic. Literally hundreds of nuclear particles have been observed and carefully measured at enormous expense. So we start the analysis of mass by considering nuclear particles.

## Nuclear Particles

Events that are highly symmetric combinations of at least sixteen Anaxagorean sensations are called *nuclear* events. Nuclear events are objectified as **nuclear particles**. They are modeled by bundles of quarks. Pions need just eight quarks, whereas the Higgs boson requires hundreds.

Nuclear particles must be highly symmetric so that they are stable enough to be measured, but not exactly symmetric. A few small asymmetries are needed or else an event would be indistinct and nondescript. Most nuclear particles are objectified from slightly different numbers of opposing binary sensations so that they have an angular momentum quantum number, baryon number, lepton number, charge and strangeness that are within two or three units of zero.

The way that these small asymmetries are balanced against each other determines a particle’s stability or *lifetime*. The most stable nuclear particles are the *proton* and the *electron*, so they get the most attention and are discussed below. But later, we also show a way of classifying dozens of other more ephemeral particles into 24 families based on their quark content.

## Mass

Let particle P be characterized by its enthalpy and the work required to bring together its component quarks. Then the **rest mass** of P is defined by

Mass | Definition |
---|---|

heavy | |

material | |

ethereal | |

imaginary |

where is a constant. This definition distinguishes several types of particles by their mass. If is positive then P is a *material* particle; an ordinary particle of matter, like a coin or a bullet. There is an important special case for material particles when the work required to make them is negligible compared to their enthalpy, then we say they are *heavy* particles.

If the mass is zero then P is *ethereal*. And if then P has an *imaginary* mass.^{1}The term *imaginary* is used here with its mathematical meaning. Particles with an imaginary mass are no more fictitious than any other sort of nuclear particle. They carry momentum and transmit forces like other particles. The main thing about having an imaginary mass is that it puts a particle in a logical category that is different from Newtonian particles. So they are not necessarily required to follow Newtonian laws of motion.

Roughly speaking, the rest mass describes how much internal energy is leftover after the work of assembling a particle has been completed. We may use the mass to describe the hardness or *density* of a particle. Recall that is the norm of the radius vector of P. Then the **density** of P is defined as

Particles and anti-particles have the same mass as each other. We have already seen how and when conjugate symmetry is assumed. But the mass depends on these quantities squared. So

Photons are ethereal because they are mostly phase anti-symmetric. The radius vector of a photon is null, and so no work is required to assemble the quarks in a photon, . Phase anti-symmetry also means that the net number of quarks is nil. Substituting this condition into the definition of enthalpy shows that as well. Then the definition of mass given above implies that

Sensory interpretation: Enthalpy characterizes the magnitude of all classes of sensation, whereas the work represents just somatic and visual sensations. The mass is established by their difference, which is mostly due to thermal sensation. So for heavy particles, thermal perceptions are more important than visual sensations. And for particles with an imaginary mass, audio-visual sensations dominate awareness.

## Lifetime

Recall that the reference sensation of touching ice is used to calibrate the measurement of temperature. So to make good measurements we are getting more precise about what we mean by *ice*. Accordingly, here is a definition of temperature that is tied to the triple point of water. The **thermodynamic temperature** is defined by

where is the Celsius temperature. In the following discussion, the symbol refers to the thermodynamic temperature, in units called *kelvins*, noted by (K).

Quarks are conserved but compound quarks may decay. Their stability is characterized by a number called the *mean-life*. Let particle P be described by its thermodynamic temperature . The **mean life** of P is defined as

where notes the exponential function and the constant seconds. Customarily, if P is an atom of hydrogen in its ground-state, then and , so this constant is called the *mean-life of hydrogen*^{2}For more detail, see the discussion of stability in the article about atomic hydrogen..

A particle with a negative temperature supposedly has a longer mean-life than hydrogen. But for EthnoPhysics, the only particles like this are some quarks and field quanta which are not given space-time descriptions. All models of observed nuclear particles have a positive thermodynamic temperature. Particle stability is also characterized by a number called the **full width** which is noted by and defined as

The total number of any specific type of thermodynamic quark does not vary if ordinary-quarks are swapped with anti-quarks of the same type. And with the assumption of conjugate symmetry both kinds of quarks have the same temperature. So

Particles and their associated anti-particles have the same mean-life and full-width.

## The Proton

EthnoPhysics describes the proton by starting with an archetypal chain of events written as

where each repeated cycle is a bundle of 24 Anaxagorean sensations. The chain of events is generically called a *history* of the proton. To be exact the prototypical sensations are; eight somatic perceptions on the right-side, four on the left, four burning thermal feelings, four freezing, and finally four black visual sensations.

Each Anaxagorean sensation may be objectified to define a seed. And Aristotle refers to the primordial atomic mass^{3}Aristotle, *Physics* 203 a 21, *De Caelo* 303 a 16, and *De Anima* 404 a 4. as πανσπερμία or a **seed-aggregate**. So to make a seed-aggregate model for the proton we express as a bundle of seeds

### A Quark Model of the Proton

Quarks are defined by pairs of seeds. So the seed-aggregate model of the proton is further developed by associating seeds in pairs to form the following quarks

Thus a proton is represented by a bundle of twelve quarks. Here is a mathematical way of expressing the arrangement, along with an iconic image for the model.

Using these quarks, the mass of the proton is calculated to be (MeV/c^{2}). This is exactly the same as the experimentally observed value because adjustable parameters like quark energies have been carefully chosen^{4}The mass of the proton can be written in terms of the work, enthalpy and quark coefficients.

The resulting equation can be solved to find the internal-energy of top-quarks as . This relationship between top and bottom quarks is then used to constrain the selection of other adjustable parameters. to get this result. For more detail, please see the *Nuclear Particles* spreadsheet.

### A Ground-State Proton Model

In the foregoing model, quark coefficients are all integer multiples of two, and so the image is drawn with the back row of quarks the same as the front row. But we cannot have two identical quarks in the same bundle and still satisfy Pauli’s exclusion principle.

So the quark model is developed further with an additional requirement that the quarks in the front and back rows are out of phase with each other. That is, they are distinguished by the helicity of the reference frame as noted by or . This satisfies the definition for being in a ground-state and so the new arrangement is called a ground-state model of the proton. It is expressed mathematically as

To illustrate this model, we show quarks with a background that is dark or bright depending on their phase. Then the image above can be made into a movie that uses shadows, horizons and background brightness to suggest a quark’s relationship with the frame-of-reference.

### Proton Stability

The temperature of a proton in its ground-state is easily calculated from the quark average

This is within experimental uncertainty of the observed^{5}Fixsen, D. J., *Temperature of the Cosmic Microwave Background*, The Astrophysical Journal **707** (2): 916–920 (2009). value of (K) for the thermal black body spectrum of the microwave background radiation. It is common to describe this background radiation as ‘cosmic’ and to assert that it comes from a ‘big-bang’. But seeing protons, bare naked in their ground-states, could offer another explanation.

The proton temperature corresponds to a calculated mean life of seconds, which is consistent with the observed^{6}K.A. Olive et al. Particle Data Group *Review of Particle Physics*, Chin. Phys. C, **38**, 090001 (2014). lower bound of seconds. So the proton is an extremely stable particle. This gives it a starring role in narratives connecting cause and effect.

## The Electron

EthnoPhysics describes the electron by starting with an a chain of events written as

where each repeated cycle is a bundle of 40 Anaxagorean sensations. The chain of events is generically called a *history* of the electron. To be exact, the sensations are eight right-side and twelve left-side somatic feelings; two burning, two freezing, two warm and two cool thermal perceptions; four yellow, four blue and four white visual sensations.

Each of these Anaxagorean sensations may be objectified to define a seed. And so to make a seed-aggregate model of the electron we express as a bundle of seeds

### A Quark Model of the Electron

Quarks are defined by pairs of seeds. So the seed-aggregate model of the electron is further developed by associating seeds in pairs to form the following quarks

Thus an electron is represented by a bundle of twenty quarks. Here is a mathematical way of expressing the arrangement, along with an iconic image for the model.

Using these quarks, the mass of the electron is calculated to be (MeV/c^{2}). This is exactly the same as the experimentally observed value because adjustable parameters like quark energies have been carefully chosen^{7}The mass of the electron can be written in terms of the work, enthalpy and quark coefficients. The resulting quadratic equation can be solved to find the internal-energy of up-quarks as

where This relationship is then used to constrain the selection of other adjustable parameters. to get this result. For more detail, please see the *Nuclear Particles* spreadsheet.

### A Ground-State Electron Model

In the foregoing model, quark coefficients are all integer multiples of two, and so the image is drawn with the back row of quarks the same as the front row. But we cannot have two identical quarks in the same bundle and still satisfy Pauli’s exclusion principle.

So the quark model is developed further with an additional requirement that the quarks in the front and back rows are out of phase with each other. That is, they are distinguished by the helicity of the reference frame as noted by or This satisfies the definition for being in a ground-state and so the new arrangement is called a ground-state model of the electron. It is expressed mathematically as

To illustrate this model, we show quarks with a background that is dark or bright depending on their phase. Then the image above can be made into a short movie that uses shadows, horizons and background brightness to suggest a quark’s relationship with the frame-of-reference.

## Gravitons

The union of a photon and its corresponding anti-photon is noted by the symbol and called a **graviton**

Let and note the number of up seeds and down seeds in a particle. And recall that seeds are conserved. So the foregoing definition of a graviton implies that

Swapping quarks with anti-quarks does not change thermodynamic seed counts, so and . Then the seed coefficients of the graviton are given by

Using these values, the angular momentum quantum number of a graviton is found as

But by definition the angular momentum quantum number of *any* photon is one. So for all gravitons

Gravitons are defined by the union of a photon with its matching anti-photon. So the net number of any sort of quark in a graviton is zero. This specifically includes down quarks. Photons have mismatched quantities of down-quarks and down anti-quarks. But for gravitons, these imbalances cancel each other perfectly so that for *all* types of quarks. Substituting these conditions into the definitions for charge, strangeness, lepton number, baryon number and enthalpy gives

Then recall that the lepton-number, baryon-number and charge are conserved, so any particle may freely absorb or emit countless gravitons without altering its own values for these quantum numbers.

Since no work is required to assemble the quarks in a graviton

This result is combined with the null value for the enthalpy to find the mass of a graviton as

So gravitons have no mass, they are ethereal.

### Graviton Location

When some particle P absorbs a graviton, we say that the graviton is located at P’s **center of gravity**. To be more exact, let us assess the radius vector for a graviton. Recall that is defined from sums of quark coefficients, and quarks are conserved. So

But as discussed earlier, any particle and its anti-particle have symmetrically opposed radius vectors, so

Thus the graviton is located at the origin of a quark space that is centered on P. So we say that the center of gravity is at the center of P. And since for all types of quarks, including down-quarks, the inner radius of any graviton is nil

An inner radius of zero means the graviton can be in P’s core. So overall, the center-of-gravity, the center-of-P and the core-of-P are all understood to be in the same location.

### Examples of Gravitons

There is a lot more to be said about gravitons and gravity, but next we look at the Classification of Nuclear Particles
