Study of Dynamics of $D^0\to K^{-}{e}^{+}{\nu }_e$ and $D^0\to {\pi }^{-}{e}^{+}{\nu }_e$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +400

In an analysis of a 2.92~fb${}^{-1}$ data sample taken at 3.773~GeV with the BESIII detector operated at the BEPCII collider, we measure the absolute decay branching fractions to be…
