Christoph Bobeth (TUM Institute for Advanced Study, Germany) - Some developments in rare B decays.

Wednesday, 4 April 2018 from to (Europe/Rome)
at Aula B
Description
After a review of tensions in charged-current and rare B decays and their
interpretation in scenarios beyond the SM, I focus on some developments that
aim to improve theoretical control. Progress on QED corrections to leptonic
decays B_s -> mu mu and B_u -> mu nu has been made, to match the future precision
at the percent level to determine short-distance quantities. A novel parameterization
ofthe hadronic charm contribution in rare b-> s ll decays allows combined analysis
of b->s ll and  b-> s (ccbar) -> ll decays to separate hadronic contributions
from new physics signals.
