Future Challenges in Non-Leptonic B Decays: Theory and Experiment

14 Jan 2019, 08:00 → 18 Jan 2019, 18:00 Europe/Berlin

02.430 (Mainz Institute for Theoretical Physics, Johannes Gutenberg University)

Indirect searches at the precision frontier are of crucial importance to test the Standard Model, search for new physics, and if found, to fingerprint it. Quark flavor processes are central to this enterprise. Of these, non-leptonic decays of B mesons offer powerful tests of the Standard Model and unique opportunities to search for New Physics. In the coming years, impressive amounts of experimental data on non-leptonic processes will be accumulated, mainly by the ​LHC and ​Belle-II​. This will lead to an unprecedented precision of the different observables, which in order to be fully exploited requires a synergy of both theoretical and experimental efforts. The objective of this workshop is to bring together both theorists and experimentalists to devise a future strategy for the analysis of non-leptonic B decays, joining efforts coherently to make the most out of the upcoming experimental data.
