First Measurement of the Decay Dynamics in the Semileptonic Transition of the $D^{+ (0)}$ into the Axial-vector Meson $K ˉ_{1} (1270)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

Using $e^{+} e^{-}$ data taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 20.3 fb $^{- 1}$ , we report the first measu…
