Thermal leptogenesis in the presence of helical hypermagnetic fields

possible explanation for this phenomenon is thermal leptogenesis, which involves. In this paper, after reviewing the thermal leptogenesis and baryogenesis through the U-Y(1 that in the combined scenario, leptogenesis and b...

Gravitational waves-tomography of Low-Scale-Leptogenesis

A long-lived scalar field (Φ) which couples weakly to the right-handed (RH) neutrinos (NRiRi​), generates small RH neutrino masses (Mii​) in Low-Scale-Leptogenesis (LSL) mechanisms, despite having a large vacuum expectation value vΦΦ​. In th...

Gravitational wave complementarity and impact of NANOGrav data on gravitational leptogenesis

(SGWB) sourced by a cosmic string network could be a potential probe of leptogenesis. We show that the leptogenesis mechanism that facilitates the dominant production that for a successful leptogenesis, an exclusion limit ...

Leptogenesis in the minimal flipped SU(5) (5) unification

We study the prospects of thermal leptogenesis in the framework of the minimal flipped SU(5) ( 5 ) unified model in which the right-handed (RH) neutrino mass scale emerges as a two-loop effect. Despite its strong suppression with respect to ...

Thermal relics in cosmology with bulk viscosity

In this paper we discuss some consequences of cosmological models in which the primordial cosmic matter is described by a relativistic imperfect fluid. The latter takes into account the dissipative effects (bulk viscosity) arising from different cool...

Testing super heavy dark matter from primordial black holes with gravitational waves

Ultra-light primordial black holes with masses M BHBH​ < 1099 g evaporate before big-bang nucleosynthesis producing all matter fields, including dark matter, in particular super-heavy dark matter: M DMDM​ ≳ 101010 GeV. If the dark matter gets its mas...
