00925njm 22002777a 4500 dc López Maroto, Antonio author Peláez Sagredo, José Ramón author 2001-04 We review our results on the calculation of helicity ±1/2 gravitino production during preheating. The method we present is based on the equivalence between goldstinos and longitudinal gravitinos at high energies. The problem is thus reduced to the standard (Majorana) fermion production after inflation. Comparison between helicity ±3/2 and ±1/2 production and with the results obtained in the unitary gauge is also presented. 0920-5632 10.1016/S0920-5632(01)01052-0 https://hdl.handle.net/20.500.14352/59330 http://dx.doi.org/10.1016/S0920-5632(01)01052-0 http://www.sciencedirect.com/ http://arxiv.org/abs/hep-ph/0012083 Gravitino production during preheating and the equivalence theorem
