Primordial features as probes of baryogenesis from supersymmetric flat directions
Yi-Peng Wu, Xingang Chen, Nino Ephremidze +1
The Affleck-Dine mechanism is a leading baryogenesis scenario in which scalar condensates form coherently during inflation along supersymmetric flat directions that are lifted by s…
Baryogenesis from ultra-slow-roll inflation
Yi-Peng Wu, Elena Pinetti, Kalliopi Petraki +1
The ultra-slow-roll (USR) inflation represents a class of single-field models with sharp deceleration of the rolling dynamics on small scales, leading to a significantly enhanced p…
Stochastic Baryogenesis
Yi-Peng Wu, Kalliopi Petraki
Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global symmetry t…
Leptogenesis from spontaneous symmetry breaking during inflation
Yi-Peng Wu, Louis Yang, Alexander Kusenko
Symmetry breaking in the Higgs field via a non-minimal coupling to gravity or higher-dimensional interactions with the inflaton can lead to condensation at a large vacuum expectati…
Higgs as heavy-lifted physics during inflation
Yi-Peng Wu
Signals of heavy particle production during inflation are encoded as non-analytic momentum scaling in primordial non-Gaussianity. These non-analytic signatures can be sourced by St…
