554. Semileptonic and Leptonic B Physics at Belle II / Priyanka Cheema [BELLE2-TALK-DRAFT-2022-167] [BELLE2-TALK-CONF-2022-136]
07 November 2022
/ 4th World Summit on Exploring the Dark Side of the Universe (EDSU 2022)
Semileptonic decays of B mesons that proceed via b->c and b->u transitions, as well as rare leptonic B decays, are fertile grounds for probing new physics beyond the Standard Model. [...]
