Production of high-energy gravitinos during preheating
A. L. Maroto, J. R. Pelaez
Abstract
We present a new technique for the calculation of helicity 1/2 gravitino production during preheating. It is based on the equivalence between goldstinos and helicity 1/2 gravitinos at high energies. The problem is thus reduced to the standard (Majorana) fermion production after inflation. Comparison with the results obtained in the unitary gauge is also presented.
