Right sneutrino with masses as non-thermal dark matter
Avirup Ghosh, Tanmoy Mondal, Biswarup Mukhopadhyaya
We consider MSSM with right-chiral neutrino superfields with Majorana masses, where the lightest right-handed sneutrino dominated scalars constitutes non-thermal dark matter (DM).…
Long-lived stau, sneutrino dark matter and right-slepton spectrum
Shankha Banerjee, Geneviève Bélanger, Avirup Ghosh +1
The minimal supersymmetric (SUSY) standard model (MSSM) augmented by right chiral sneutrinos may lead to one such sneutrino serving as the lightest supersymmetric particle and a no…
Boundary Conservation from Bulk Symmetry
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
The evolution of the black hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matte…
Black Hole Entropy production and Transport coefficients in Lovelock Gravity
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of null Raychaudhuri equation. We show that the similarity between t…
