Description
In the Standard Model (SM) of particle physics, fermions exhibit a peculiar hierarchical pattern, most notably in their masses, quark flavor mixing, and charged-current weak interactions. The origin of this flavor structure remains unknown within the SM. Hence, testing these flavor phenomena experimentally provides a vital probe for new physics beyond the SM (BSM) and deeper underlying principles.
In this talk, we present recent experimental highlights in quark flavor physics, focusing on results from Belle II, LHCb, BESIII, and other experiments. Covered topics include updates on tests of lepton flavor universality (such as $R(D^{(*)})$), measurements of time-dependent CP violation in $B^0 \to \pi^0 \pi^0$ utilizing quantum entanglement, and recent results on $B$ decays with missing energy in the final state.
