Late-time Entropy Production from Scalar Decay and Neutrino Decoupling
Paramita Adhya, D. Rai Chaudhuri
Late-time entropy production from scalar decay arises in scenarios like thermal inflation, proposed to dilute long-lived, massive fields like the gravitino and the moduli. The scal…
Entropy Production during Reheating at Late Times and Neutrino Decoupling
Paramita Adhya, D. Rai Chaudhuri
Small Recent theories have proposed a variety of massive particles, like the moduli, whose abundance or decay endangers standard cosmological results. To dilute them, thermal infla…
Decay and Decoupling of heavy Right-handed Majorana Neutrinos in the L-R model
Paramita Adhya, D. Rai Chaudhuri, Amitava Raychaudhuri
Heavy right-handed neutrinos are of current interest. The interactions and decay of such neutrinos determine their decoupling epoch during the evolution of the universe. This in tu…
Decoupling of Massive Right-handed Neutrinos
Paramita Adhya, D. Rai Chaudhuri
We investigate the effect of B+L - violating anomalous generation of massive right-handed neutrinos on their decoupling, when the right-handed neutrino mass is considerably greater…
