Description
Charm physics at the LHC offers exciting prospects to probe beyond the Standard Model phenomena. Particularly interesting is the connection between the top and the charm, as they belong to the same flavour representation, thus creating a potential link between top-charm physics and the dynamics of extended sectors of the SM responsible for the stabilization of the electroweak scale. The charm quark, on the other hand, poses difficult challenges to both the experimental measurements, and their theoretical interpretation. Its not-so-heavy mass limits the precision of theoretical predictions for processes like flavour-changing neutral currents or CP violation, as well as predictions for its production dynamics. Experimentally, charm jets interpolate between ordinary QCD jets and b-jets in their physical properties, and are therefore hard to identify.

The LHC experiments have now proven their ability tag high-pt charm jets, a significant milestone in improving their sensitivity to non-standard model charm physics. In addition, the LHCb experiment is in a position to significantly improve its sensitivity to CP violation in D-Dbar mixing this year. It is therefore a timely moment to analyze the experimental and theoretical status of non-standard charm physics.

This CERN-TH/LPCC workshop will bring together experimental and theory experts from the various frontiers relevant to top and charm physics, to cover all aspects of charm identification, charm production via SM and BSM processes, charm decays, and BSM model building related to charm quarks. The goal is to discuss how the expected experimental progress might lead to improve our sensitivity to new physics using the existing LHC data, as well as in view of the next LHC run.
