1. Study of the D0Kμ+νμ Dynamics and Test of Lepton Flavor Universality with D0K+ν Decays / Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; Albrecht, M. ; et al
Using e+e annihilation data of 2.93 fb1 collected at center-of-mass energy s=3.773 GeV with the BESIII detector, we measure the absolute branching fraction of D0Kμ+νμ with significantly improved precision: BD0Kμ+νμ=(3.413±0.019stat±0.035syst)%. [...]
