From its humble beginnings as a 3-channel mixing measurement to be parasitically performed with RICH calibration samples, the charm physics programme at LHCb expanded in scope to what is now a major component of LHCb’s contribution to science. Now with the largest samples of charmed hadrons ever produced (that continue to grow!), LHCb is providing insight into the physics of charm with...
Lattice QCD has entered a precision era in the charm sector, with predictions for the charm quark mass available at percent level precision. Uncertainties are now dominated by systematic effects arising from discretisation and renormalisation. We present two novel approaches for controlling these effects: a massive momentum-subtraction scheme, and gradient flow combined with short-flow-time...
Searches for new beyond the Standard Model (BSM) physics at the ATLAS experiment typically target particles that decay promptly, very close to the collision point. New physics has so far evaded these searches. Multiple BSM models predict new long-lived particles (LLPs) that are produced at the interaction point with decay lengths ranging from millimetres to kilometres. In new physics...
50 years after the discovery of the first charmed particle, charm physics continues to be an extremely lively field of research and a cornerstone in particle physics. The study of charm, with its unique properties, is characterised by many challenging but also exciting peculiarities, making it an ideal testing ground for Standard Model (SM) predictions and a very sensitive probe of new...
