Title: Is leptogenesis during post-inflationary reheating flavourful?

Speaker: Dr. Arghyajit Datta (Jeonbuk Natl. U.)

Abstract: Abstract: We show that the process of non-instantaneous reheating during the post-inflationary period can
have a sizable impact on the charged lepton Yukawa equilibration temperature in the early Universe.
This suggests relooking the effects of lepton flavors in the leptogenesis scenario where the production
and decay of right-handed neutrinos take place within this prolonged era of reheating. We find this
observation has the potential to shift the flavor regime(s) of leptogenesis compared to the standard
thermal scenario.
