Leptogenesis and low-energy CP-violation

Date and Time: Friday, November 06, 2020, 04:00pm -
Location: Zoom

Speaker:  Jessica Turner, Fermi National Accelerator Laboratory 

AbstractI will provide a general overview of the matter anti-matter asymmetry and how this can be linked to the generation of light neutrino masses. I will discuss the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix. I will demonstrate the viability of thermal leptogenesis across seven orders of magnitude and clarify that at very high scales T > 10^12 GeV is sensitive to the low-energy phases, in contradiction with what is usually claimed in the literature.
