Delayed Charged Lepton Yukawa Equilibration in Minimal Seesaw
Rishav Roshan, Sudipta Show
While most studies of the \textit{minimal type-I seesaw} neglect the heaviest decoupled right-handed neutrino, assuming negligible contributions to neutrino masses and leptogenesis…
Boomerang mechanism explaining the excess radio background
Bhupal Dev, Pasquale Di Bari, Ivan Martinez-Soler +1
We propose a boomerang mechanism for the explanation of the excess radio background detected by ARCADE 2. In an early stage of the Universe, at a temperature in the range $\sim…
Freeze-In Dark Matter and Leptogenesis: a SM route
Adeela Afzal, Rishav Roshan
We investigate the possibility of \emph{freeze-in} dark matter production and baryogenesis via leptogenesis in a SM model, which is an extension of the Standard Model, fe…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Cosmological Consequences of Domain Walls Biased by Quantum Gravity
Yann Gouttenoire, Stephen F. King, Rishav Roshan +3
One of the simplest standard model extensions leading to a domain wall network is a real scalar with a symmetry spontaneously broken during universe evolution. Motivated…
