**Praons** is the general name for a family of hypothetical
particles, consisting of neutral n-praons and positively charged p-praons. In
the theory of Infinite Hierarchical Nesting of Matter, praons are similar in their properties to
nucleons, that is, to neutrons and protons. To assess the properties of praons,
the similarity of matter levels is used. It is assumed that praons consist of
graons in a similar way as nucleons consist of praons, and neutron stars
consist of nucleons. Ultrarelativistic flows of praons are one of
the components of the electrogravitational
vacuum, which, along
with the streams of graons, are responsible for the occurrence of gravity and
electromagnetic interaction. ^{[1]}

**Origin**

Supposing that SPФ
symmetry is valid at all levels of
matter, the laws of nature act in the same way at these levels. Hence we can
assume that as nucleons form the ordinary matter, so praons are the basis of
the matter from which nucleons, electrons and other particles are composed. A
typical neutron star contains approximately *Ф* = 1.62∙10^{57 }nucleons, and the same
number of praons is expected inside each nucleon. This allows us to understand
why in accelerators in collisions of nucleons with particles of the highest
energy, decay products behave like liquid plasma jets, and no fairly large
particles, such as partons or individual quarks, are detected. It is assumed that 61% of all praons
in the Universe are part of nucleons, and 39% form dark matter, including part
of nuons. ^{[2]}

In general, we can talk about
the wave of matter evolution in the Universe. A typical scenario for the appearance
of a neutron star is as follows: first, under the action of gravitation
compression of a large gas cloud takes place, in which the primary stars
emerge. The evolution of a star of sufficient mass ends with a
supernova and birth of a neutron star, and the evolution of the low-mass stars
turn into white dwarfs. Thus,
before the appearance of compact star remnants, there must have been the matter
in the form of gas. Similarly, we can imagine that the existence of the matter
of praons in the form of gas eventually led to the formation of the matter of
nucleons such as hydrogen gas clouds. The wave of evolution in this case moves
in the direction from the lower levels of matter to the higher levels of
matter, from the smallest particles, such as graons, to praons, then to
nucleons, neutron stars and to even larger objects. Since each basic level of
matter generates its own fluxes of relativistic particles and wave quanta that
generate fundamental interactions, such as gravitation and electromagnetism
based on the mechanism of Le Sage’s gravitation, then the wave of evolution
also refers to fundamental interactions. This means that emergence of objects
of a certain level of matter would be impossible if there would be no
sufficiently large number of particles of the lower levels of matter and no
fluxes of relativistic particles, generated by them and making their
contribution into the multicomponent vacuum force field.

**Properties**

A typical neutron star has the
mass of 1.35 Solar masses, the radius of the order of 12 km, and the __characteristic
speed__ of particles in such a star reaches 0.23 of the
speed of light. Dividing these values by the corresponding values for the
proton, we obtain the similarity coefficients: in mass *Ф** *= 1.62∙10^{57 }, in sizes *Р** *= 1.4∙10^{19 }, and in speed *S *= 2.3∙10^{– 1 }. In the first
approximation, we can assume that the same similarity coefficients in mass and sizes
are also valid for the relationship between praons and nucleons. Hence we
determine the praon mass kg and
its radius m, in
this case we used the proton radius m. ^{[3]}
Using the mass and radius of the praon we can estimate the average density of
its matter kg /m^{3
}.

The characteristic speed for
the particles of matter inside the proton and praon is close enough to the speed
of light. In this case, instead of the particles’ speed it is convenient to use
their Lorentz
factor. In the __relativistic uniform
model__, there is a formula for the dependence of the
Lorentz factor on the current radius inside the system of particles of a
spherical shape, held in equilibrium by the gravitation force and the force of
internal pressure: ^{[4]}

where is the
speed of light, is the
Lorentz factor of the particles at the center of the sphere, is the
current radius, is the
invariant mass density of the system’s particles, is the
coefficient of the __acceleration field__.

In such objects as the neutron
star, proton, and also praon, the average mass density does not differ much from
the central mass density, so that this formula must provide the correct order
of magnitude of the Lorentz factor. We will now use the expression for the rest
mass of a spherical body:

If we substitute here the
neutron star’s mass instead of , the
star’s radius instead of , and use the average mass density instead of , and
also take into account the equality , ^{[5]}
where is the __gravitational
constant__, then we can calculate the Lorentz factor for
the nucleons at the center of the star: . The similar approach can be applied to the
proton, with the difference that instead of the ordinary gravitational constant
we should use the __strong gravitational constant __ m^{3}•s^{–2}•kg^{–1}.
So it turns out that at the center of the proton the Lorentz factor for the
praons, located there, equals 1.9. ^{[6]}

Finally, for the praon it is
necessary to use the gravitational constant
, acting at its level of matter.

To estimate this constant, we can apply the
similarity relations between the levels of praons and nucleons: . Hence
it follows that the value of the praon’s gravitational constant is m^{3}•s^{–2}•kg^{–1}. After substituting
into (2) the mass, radius and density of the praon, taking into account the
equality , we find the Lorentz factor for graons at the
center of the praon, which is approximately equal to 64.

The typical angular momentum at each level of
matter is given by the Dirac
constant. For compact stars J∙s, for
the nucleons’ level of matter J∙s,
while the quantum spin of the nucleon is equal to . To estimate the Dirac constant at the
level of praons, the following similarity relation can be used: . Hence it turns out that J∙s.

The Boltzmann constant for the level of praons
is given by the expression: J/K,
where is the Boltzmann
constant.

For the strong gravitational constant the
following relation holds true:

Where is the elementary
charge, is the __electric
constant__, is the
proton mass, is the
electron mass, is the ratio of the proton mass to the
electron mass. Similarly, at the level of praons we obtain the following:

Hence we find the praon’s charge C. If we
use the theory of similarity, then the charge of the praon is expressed through
the charge of the proton (elementary charge) and the coefficients of similarity
as follows: C .

By analogy with a free neutron, which undergoes
beta-decay in seconds,
we can estimate the lifetime of a free
neutral n-praon. To do this, we can use the similarity relation , which gives
seconds.

**Wave quanta**

It is assumed that praons are
not only “the building material” for nucleons and electrons that form the
matter, but also they make up the composition of all hadrons and leptons.
Moreover, such wave quanta as photons should also consist of praons. During transition
of the excited electron in the atom to the state with lower energy, the center
of the electron cloud is shifted relative to the nucleus, which leads to the
quantum spin of the electron (see __substantial electron
model__). In this case, the periodic electromagnetic field
of the rotating electron appears, acting on the fluxes of the vacuum field’s
praons and making up a photon of them. In the substantial photon model, praons
are closely associated with the __strong gravitation__ and
form sufficiently rigid wave structure of the photon, rotating during its
motion. ^{[7]} For the case of
the electron transition from the second level to the first level in the
hydrogen atom, when a photon with the angular frequency s ^{-1 }is emitted in the Lyman series, the
total rest mass of all the praons of such a photon is equal to kg. If we
divide the mass by the rest
mass of one praon kg, we
can estimate the number of praons in this photon: .

Let us now consider the electron
antineutrino emitted in the free
neutron decay. If from
the energy of the neutron at rest we subtract the rest energy of the proton and
the electron, arising from the decay, then the energy obtained will be equal to
the antineutrino energy, to which we must add the sum of the kinetic energies
of the electron and the proton. In the limiting case, the sum of the kinetic
energies of the electron and the proton is minimal, and the antineutrino energy
reaches the maximum possible value of keV or J. If we
denote by the
total rest mass of all the particles making up the antineutrino, then for the
antineutrino energy we can write: , where is the speed of light. Hence, with the Lorentz factor equal to , as in the case of the photon, we can estimate
the antineutrino mass: kg. It
turns out that the mass of all the particles of this antineutrino is 4.6 times
greater than the mass of praons in the photon, emitted in the hydrogen atom at
the angular frequency s^{-1 }in
the Lyman series.

According to the __substantial neutron
model__, the electron antineutrino, emitted from the
neutron in its beta decay, is made of the praantineutrinos and praneutrinos,
which arise respectively in the beta decay of n-praons, that compose the
neutron, and in the capture of praelectrons by p-praons, that is, in the weak
interaction reactions, but already at the level of matter of praons. ^{[}^{8]} This
means that the electron antineutrino consists of multiple parallel fluxes of
the vacuum field’s graons, while each of these fluxes is formed at the moment
when the corresponding neutron’s praon is transformed in the weak interaction
reaction. The parallel
alignment of the graon fluxes is due to the fact that the magnetic moments of
the praons inside the neutron are directed by the strong magnetic field of
the neutron. Antineutrino by its form represents a cylindrical
object moving at the speed of light, with the cross-section equal to the
cross-section of the neutron. The right helicity of antineutrinos means that
the graon fluxes are
twisted to the right relative to the direction of motion of antineutrinos,
which coincides with the spin direction of the decaying neutron. The stability
of antineutrinos is maintained by the strong gravitation acting at the level of
graons and by electromagnetic forces.

It is assumed that the emission time of an
antineutrino during the decay of a free neutron should be comparable with the
lifetime of free n-praons seconds.

For comparison, we can consider the formation of a
neutron star in a supernova, which occurs with the emission of neutrino and
antineutrino fluxes with a total duration of the order of seconds. At the level of the matter of
nucleons, such a process can be considered as the formation of a neutron, with
the emission of fluxes of praantineutrinos and praneutrinos. The radiation time
is estimated as seconds at .

From this we see that the
structures of the photon and the antineutrino are absolutely different, they also
differ in the composition of their main particles. Being composed of the
smallest graons, neutrinos and antineutrinos have an extremely high penetrating
ability, in spite of the fact that they have energies and rest masses
comparable with those of photons.
