Production of high-energy gravitinos during preheating
We present a new technique for the calculation of helicity $\pm 1/2$gravitino production during preheating. It is based on the equivalence betweengoldstinos and helicity $\pm 1/2$ gravitinos at high energies. The problem isthus reduced to the standard (Majorana) fermion production after inflation.Co...
