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

610th WE Heraeus-Seminar 

Testing the Standard Model and searching for New Physics are among the main priorities in High-Energy Physics. Whether or not new particles are directly produced at the LHC, indirect searches will remain crucially important 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 unique opportunities, and large amounts of experimental data will be produced in the coming years, mainly at the LHC and Belle-II.

The objective of this workshop is to bring together 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 new experimental data.

Organization pannel:  Javier Virto, Tobias Huber, Thomas Mannel. Theoretische Physik 1, Naturwissenschaftlich-Technische Fakultät, Universität Siegen, 57068, Deutschland

This workshop is generously funded by the WE-Heraeus Stiftung and corresponds to the 610th Wilhelm und Else Heraeus-Seminar. It will take place at the Physikzentrum Bad Honnef.
