  1. 4. Higgs to tau and charm
    Harald Fox (Lancaster University)

  2. 1. Theory of Charm CP Violation
    Stefan Schacht
    11/02/2026, 11:55

    Charm CP violation is a unique gate to the flavour structure of up-type quarks and allows for searches for physics beyond the Standard Model in new and exciting ways, complementary to kaon and b decays. After its discovery by LHCb in 2019, we are still at the beginning of the exploration of the nature of the violation of CP by charm quarks. We discuss the most recent developments which allowed...

  3. 2. Recent charm results from LHCb
    Patrick Spradlin (University of Glasgow)
    11/02/2026, 14:00

    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...

  4. 5. Charm Quark Mass from Lattice QCD
    Matthew Black (University of Edinburgh), Rajnandini Mukherjee (University of Edinburgh)
    11/02/2026, 14:50

    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...

  5. 6. Displaced tau jets: An exercise in unconventional signatures at the ATLAS experiment
    Alex Veltman (The University of Edinburgh)
    11/02/2026, 16:10

    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...

  6. 3. The short lifetime of charm
    Alexander Lenz (IPPP, Durham)
    11/02/2026, 16:25

    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...
