First Amplitude Analysis of $D^0\to K^{-}\ddot{I}{€}^0{e}^{+}\hat{I}{½}_e$ and Observation of $D^0\to K_2^{\ast }(1430{)}^{-}{e}^{+}\hat{I}{½}_e$

BESIII Collaboration, M. Ablikim, M. N. Achasov +687

We present the first amplitude analysis of the semileptonic decay $D^0\to K^{-}\ddot{I}{€}^0{e}^{+}\hat{I}{½}_e$ by analyzing $e^{+}{e}^{-}$ annihilation data corresponding to an integrated luminosity of…
