Search for the radiative leptonic decay $D^{+}\to \gamma e^{+}{\nu }_e$ using Deep Learning

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Using 20.3$\mathrm{f}{\mathrm{b}}^{-1}$ of $e^{+}{e}^{-}$ annihilation data collected at a center-of-mass energy of 3.773$\mathrm{GeV}$ with the BESIII detector, we report an improved search for the radiat…
