Charm physics at the Belle and Belle II experiments
/ Longke Li
[BELLE2-CONF-PROC-2024-011]
presented at the 2024 International Workshop on Future Tau Charm Facilities (FCTF 2024). The slides are available in BELLE2-TALK-CONF-2024-001.
17 May 2024
We present recent results on charm physics at the Belle and Belle II experiments, covering measurements of charm lifetimes, branching fractions of the decays of charmed mesons and baryons and the decay asymmetry parameters of two-body decays of charmed baryons, searches for rare and forbidden decays, and measurements of $C\!P$ violating parameters in the four-body decays of charmed mesons and two-body decays of charmed baryons [...]
