Inflation, as a tool for supersymmetry breaking

[pleasehelpmeno]

Hi
I know that gravitninos are produced in the Early Universe in reheating (after inflation), is this because the end of inflation/reheating period where the inflaton is oscillating about the minima of the potential is analogous to symmetry breaking?

You realize that gravitinos and gravitons have not been observed right?

 

[pleasehelpmeno]

yes but if susy does exist, gravitinos would be produced after inflation.

Can't really help much as I am
not too familiar with Susy.
however this article may help

Yes, the process of inflation can be seen as a tool for supersymmetry breaking. During inflation, the inflaton field drives the rapid expansion of the universe, causing a temporary shift in the energy density of the universe. This shift in energy density can lead to the breaking of supersymmetry, which is a fundamental symmetry between particles and their superpartners.

As the universe expands and cools down, the inflaton field eventually reaches the bottom of its potential and begins to oscillate. This is similar to the process of symmetry breaking, where a field settles into a minimum energy state. The oscillations of the inflaton field can produce gravitinos, which are the supersymmetric partners of gravitons.

Therefore, the end of inflation and the reheating period can be seen as analogous to symmetry breaking, leading to the production of gravitinos and the breaking of supersymmetry. This process is important in understanding the early universe and can have implications for particle physics and cosmology.
