“…The same selection criteria as reported in Refs. [11,[33][34][35][36] are used in this analysis. Charged tracks are required to have polar angle (θ) within j cos θj < 0.93, and except for those from K 0 S decays, are required to originate from an interaction region defined by jV xy j < 1 cm and jV z j < 10 cm, where jV xy j and jV z j refer to the distances of closest approach of the reconstructed track to the interaction point in the xy plane and the z direction (along the beam), respectively.…”

“…The uncertainty in the total ST yield, which is mainly from the uncertainty due to the M BC fit of the ST candidates, has been studied in Refs. [11,33,34] and is assigned as 0.5%. The tracking and PID efficiencies of the pion and muon are studied by analyzing the DT hadronic DD events and e þ e − → γμ þ μ − events, respectively.…”

“…The systematic uncertainties associated with the pion tracking (PID), muon tracking (PID) are assigned to be 0.2% (0.3%) and 0.3% (0.3%), respectively. The π 0 efficiency, including effects of photon selection, the 1-C kinematic fit, and the mass window, is studied with DT hadronic DD decays [33,34], and a systematic uncertainty of 0.7% is assigned to each π 0 . The uncertainty of the E max extra γ requirement is estimated to be 4.4% by analyzing the DT DD events of…”

We report the first observation of the semimuonic decay D þ → ωμ þ ν μ using an e þ e − collision data sample corresponding to an integrated luminosity of 2.93 fb −1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV. The absolute branching fraction of the D þ → ωμ þ ν μ decay is measured to be B D þ →ωμ þ ν μ ¼ ð17.7 AE 1.8 stat AE 1.1 syst Þ × 10 −4. Its ratio with the world average value of the branching fraction of the D þ → ωe þ ν e decay probes lepton flavor universality and it is determined to be B D þ →ωμ þ ν μ =B PDG D þ →ωe þ ν e ¼ 1.05 AE 0.14, in agreement with the standard model expectation within one standard deviation.
