Some new ideas in Leptogenesis and Dark Matter studies

Rome Samanta (Southampton Univ.)

27 Novembre 2019 @ 11:00 - 13:00

Type-1 seesaw is the simplest extension of the Standard Model (SM) that explains light neutrino masses and baryon asymmetry of the universe (BAU) via leptogenesis. In the first part of this talk, I shall discuss how different seesaw models can be visualised graphically and how a fine-tuning in the seesaw formula can be related to ...

Global fits to b → cτν transitions

Ana Penuelas Martinez (Valencia Univ.)

27 Novembre 2019 @ 12:00 - 14:00

We perform a general model-independent analysis of b → cτντ transitions, including measurements of RD , RD∗ , their q2 differential distributions, the recently measured longitudinal D∗ polarization FD∗, and constraints from the Bc → τντ lifetime, each L of which has significant impact on the fit. A global fit to a general set of ...
