The equivalence theorem and the production of gravitinos after inflation
We study the high-energy equivalence between helicity ±1/2 gravitinos and Goldstinos in order to calculate the production of gravitinos in time-dependent scalar and gravitational backgrounds. We derive this equivalence for equations of motion, paying attention to some subtleties, mainly due to exter...

| Resumo: | We study the high-energy equivalence between helicity ±1/2 gravitinos and Goldstinos in order to calculate the production of gravitinos in time-dependent scalar and gravitational backgrounds. We derive this equivalence for equations of motion, paying attention to some subtleties, mainly due to external sources, that are not present in the standard proofs. We also propose the Landau gauge as a simplifying alternative to the usual gauge choices, both for practical calculations and in the equivalence theorem proof. |
