Pair production is a great experience that is able helps us to answer many mysteries of universe. Pair production and annihilation is an empirical example of equivalence relation mass and energy. Dirac had solved the equation;

in form of;

Dirac had not removed negative part of its answer. He thought and analyzed it. Then he guessed there is anti-electron in nature.

This is because the process is a result of a g ray converting to an electron-positron pair. In the process, the g ray is converted to an electron positron pair as shown schematically in figure. As the positron slows down, further annihilation takes place resulting in the production of two photons.

Pair production electron and positron

Annihilation pair electron-positron

These days pair production is a usually experiment. In 1955 physicist produced proton and anti-proton in laboratory. But as mentioned in beginning of item, I will explain how charge particles produce electricity force. But attention to pair production is a great tool for this.

We know before of pair production there is a photon that has no charge. But after of pair production there are two charge particles, electron with negative charge and positron with positive charge. These charge particles have two electricity fields. We cannot passing of this phenomenon, because consideration to this fact is able to open a new way for understanding the essence of charge and effective charges.

Photon And electricity charge

Photon carries two fields, an electricity field and a magnetic field. But it is not enough to get what we are look forward. So, we return to gravitational effect on photon. But in this case we must have a new look and do summarize our results.

We saw in section 2 that a photon has mass that gives with;

m=hv/c²

So, its weight is equal;

mg=(hv/c²)g

Suppose photon fall distance y toward the earth. So, its energy reaches to;

hv'=hv+mgy

Following picture shows moving photon in gravitational field. Gravitons (color-charges and magnet-color) enter into structure of photon and its energy (mass), frequency, and intensity of electricity field and magnetic field increase.

If we consider to below relation on the earth gravitational field, only;

hv'=hv+mgy

According the amount of Plank constant and intensity of earth�s gravity, there is not important change for frequency of photon. But it is questionable in high intensity gravity fields, is this effect very considerable? Answer is yes, because there is very massive body with very high intensity gravity in the universe.

However, experiments show changing them is measurable on the earth. We accepted that photon�s energy changes and this energy is using to production pair electron and positron. Two charge particles with opposite electricity fields. Now look at;

electromagnetic energy => electric charge

Electromagnetic energy => negative and positive particle charge

They inform that;

1- Gravitational field is formed of exchangeable particles that have electricity and magnetic effect (color-charge and magnet-color).

2- Color-charges combine and produce charges particles.

3- Color-charges are two opposite sign, negative and positive that there are in the structure of photon.

4- In production matter and anti-matter, negative color-charges combine with each other, and positive color-charges combine with each other too, than they do form positive and negative charge particles (see following picture).
