Heavy Hadron Decays@CERN-TH

The field of heavy-quark flavor physics has entered the precision era, and the existing and anticipated data particularly from the LHCb, Belle II and BESIII experiments will allow for stringent tests of the Standard Model (SM). Among the multitude of different decay channels, hadronic decays of heavy mesons like $B \to D \pi$, $B \to K \pi$, etc. play a central role in challenging our current best theory of elementary particles, and in extracting its fundamental parameters. For several observables, some intriguing tensions have already been seen between the corresponding experimental data and the current SM predictions, possibly hinting at first signs of New Physics (NP). On the other hand, the theoretical description of hadronic decays is notoriously very challenging and, besides perturbative calculations, also requires the determination of hadronic parameters using non-perturbative methods like lattice QCD and QCD sum rules. Thus, a solid interpretation of the observed discrepancies can only be achieved through advances in both fields as well as a close collaboration between the theoretical and experimental communities.

This workshop will bring together experts in continuum and lattice QCD as well as experimentalists to discuss the current status of SM predictions and NP interpretations in these decay channels.
