Standard Model Baryon Number Violation at Zero Temperature from Higgs Bubble Collisions
Nabeen Bhusal, Simone Blasi, Martina Cataldi +3
We compute for the first time baryon number violation at zero temperature from Higgs bubble collisions and find that it can be of the same order as that from thermal sphalerons in…

Slow-down of expanding bubbles in the early Universe
Nabeen Bhusal, Simone Blasi, Thomas Konstandin +2
We study slow-down effects for bubbles formed in a cosmological first-order phase transition (PT) focusing on deflagrations and hybrids, where the bubble wall is preceded by a shoc…

Fermion (non)reheating with a quartic inflaton potential
Nabeen Bhusal, M. Ernesto Chávez M., Ernesto Chávez M. +3
Any viable inflationary model must account for reheating of the universe prior to the onset of primordial nucleosynthesis. In this work, we study the (p)reheating mechanism for an…
