Study of the Standard Model with weak decays of charmed hadrons at BESIII

Abstract

A comprehensive review of weak decays of charmed hadrons ($D^{0/+}$, $D_s^{+}$ and ${\Lambda }_c^{+}$) based on analyses of the threshold data from $e^{+}{e}^{-}$ annihilation in the BESIII experiment is presented. Current experimental challenges and successes in understanding decays of the charmed hadrons are discussed. Precise calibrations of QCD and tests of the Standard Model are provided by measurements of purely leptonic and semi-leptonic decays of charmed hadrons, and lepton universality is probed in purely leptonic decays of charmed mesons to three generations of leptons. Quantum correlations in threshold data samples provide access to strong phases in the neutral $D$ meson decays and probe the decay dynamics of the charmed ${\Lambda }_c$ baryon. Charm physics studies with near-threshold production of charmed particle pairs are unique to BESIII, and provide many important opportunities and challenges.
