Gauge field production in SUGRA inflation: local non-Gaussianity and primordial black holes
Andrei Linde, Sander Mooij, Enrico Pajer
When inflation is driven by a pseudo-scalar field χcoupled to vectors as α/4 χF \tilde F, this coupling may lead to a copious production of gauge quanta, which in turns induces non…
Effective action for the Abelian Higgs model in FLRW
Damien P. George, Sander Mooij, Marieke Postma
We compute the divergent contributions to the one-loop action of the U(1) Abelian Higgs model. The calculation allows for a Friedmann-Lemaitre-Robertson-Walker space-time and a tim…
Sgoldstino inflation
Ana Achúcarro, Sander Mooij, Pablo Ortiz +1
We discuss the possibility that inflation is driven by the sgoldstino, the superpartner of the goldstino. Unlike in generic supergravity scenarios, the sgoldstino decouples from al…
