Gravitational waves-tomography of Low-Scale-Leptogenesis

Original language description

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 this case, the correlation shared by the Mii​s and the duration of the non-standard cosmic history driven by the Φ provides an excellent opportunity to study LSL signatures on primordial gravitational waves (GWs). We find it engaging, specifically for the gravitational waves that originate due to the inflationary blue-tilted tensor power spectrum and propagate through the non-standard cosmic epoch. Depending on Mii​, broadly, the scenario has two significant consequences.
