We discuss how a post-inflationary reheating phase characterized by a nonstandard
multiple scalar field cosmology can change the thermal history of the Universe, affecting …

A bstract We present the possibility that the seesaw mechanism and nonthermal
leptogenesis can be investigated via primordial non-Gaussianities in the context of a …

Recently, it has been shown that the presence of a noninstantaneous era of reheating can
significantly alter the charged lepton (s) equilibration temperature (s) which plays an …

A bstract This paper investigates non-thermal leptogenesis from inflaton decays in the
minimal extension of the canonical type-I seesaw model, where a complex singlet scalar ϕ …

We study thermal and non-thermal resonant leptogenesis in a general setting where a
heavy scalar $\phi $ decays to right-handed neutrinos (RHNs) whose further out-of …

We propose novel inflationary primordial gravitational wave (GW) spectral shapes at
interferometer-based current and future GW missions to test dark matter (DM) production …
