First Amplitude Analysis of $D^0\to K^{-}{\pi }^0{e}^{+}{\nu }_e$ and Observation of $D^0\to K_2^{\ast }(1430{)}^{-}{e}^{+}{\nu }_e$

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

We present the first amplitude analysis of the semileptonic decay $D^0\to K^{-}{\pi }^0{e}^{+}{\nu }_e$ by analyzing $e^{+}{e}^{-}$ annihilation data corresponding to an integrated luminosity of 20…
