In Part 2, we have already studied two interactions, the e+e- pair production by a gamma, and the opposite effect,
the e+e- annihilation.
Since all components are made up of spacetime, it is possible that other interactions follow the same rule
as the e+e- production or annihilation.
This page covers basic interactions to establish a guideline.
According to the first principle of duality pointed out in
www.what-is-matter.com (Part 2 of the Spacetime Model), any EM wave may be transformed into a particle
We must always keep in mind that
Particles do not come from a vacuum
but from spacetime movements
For example, the following figure shows the creation of six quarks, three u and three u bar,
an e+e- pair, and a residual gamma.
All these components may be created at the same time from spacetime movements, or gammas.
In this example, the most probable scheme is the creation of a proton-antiproton pair.
However, any other particles may be created.
Of course, we must have the same quantity of electrons-positrons before and after the interaction, including the gammas.
Finally, the incoming gammas provide many possible combinations.
The same principle may be applied in high-energy interactions.
The particles' jets come from spacetime movements produced by the particle collision.
The reciprocal interaction is also possible: some particles decays in gammas, according to Feynman's diagrams
In our example, the creation of three u/u bar quarks requires the presence of two positrons-electrons
very close to each other.
The particles are created mainly due to energy, but the proximity should probably also be taken into account.
This means that any heavy particles (SUSY...) may exist and will probably be discovered
in the future since all particles are made of spacetime.
Note: This new way to consider that, in the universe, we have only three components,
electrons, positrons and sCells, does not change the current formulas in quantum mechanics or QED/QCD.
This document contains many schematics for teaching purposes.
However, sooner or later, it will be necessary to classify particles according to the Spacetime Model.
In this way, it would be useful to have a simple method of representing the internal structure of the basic
components, electrons, positrons, quarks...
The following scheme can be used.
The basis particles are e+, e-, u, ubar, d and d dbar.
A parenthesis means an electron or a positron is surrounding the other basic particles.
Of course, parenthesis must go in pairs.
d quark = (u) e-
Proton = (u, u, u) e-
Neutron = ((u, u, u) e-) e-
Antiproton = (u bar, u bar, u bar) e+
The particles that surround the others are electrons and positrons.
They act as the "strong nuclear force".
Since this force is necessary in any composite particle, meson, baryons..., we can state the following rule:
All composite particles must have at least one parenthesis pair.
It means that:
All composite particles must have
at least one electron or positron
Or, translated to nuclei:
All nuclei must have
at least one neutron
The necessity to have an electron or positron surrounding other particles probably explains why we do not see any proton
in the halo in atoms with halo.
The latter is built with neutrons (i.e. protons + electrons) only.
This new theory also explains the instability of the Li3.
