Gravitino production during preheating and the equivalence theorem López Maroto, Antonio Peláez Sagredo, José Ramón 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. 2023-06-20T19:09:39Z 2023-06-20T19:09:39Z 2023-06-20T19:09:39Z 2001-04 journal article https://hdl.handle.net/20.500.14352/59330 0920-5632 10.1016/S0920-5632(01)01052-0 eng open access Elsevier Science Bv
