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

Aula B ()

Aula B

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.
