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 various interactions follow the same rule as the e+e- production or annihilation.
Subject of the chapter
This chapter covers basic interaction to establish a guideline.
16.1 Guiding Principle
According to the first principle of duality pointed out in chapter 1,any EM wave may be transformed into a particle and the converse .We must always keep in mind that
Particles do not come from a vacuum but from spacetime movements
For example ,figure 16-1 shows the creation of six quarks,three u and three u bar,an e+e- pair,and a residual gamma.All these components are created at practically the same time from the spactime 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,inculding the gammas.Finally ,the incoming gamma provides many possible combinations.
