Radiative decays of $X (3872)$ within $D D ˉ^{*}$ molecular framework

Hao-Dong Cai, Run-Hao Chen, Yuan-Jun Gao +3

Within the framework of nonrelativistic effective field theory, we calculate the radiative decay width of the process $X (3872) \to D ˉ D γ$ while taking into account the $D\bar…

Precise measurement of the form factors in $D^{0} \to K^{} (892)^{-} ℓ^{+} ν_{ℓ}$ and observation of $D^{0} \to K_{2}^{} (1430)^{-} ℓ^{+} ν_{ℓ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

We report a study of the semileptonic decays $D^{0} \to K ˉ^{0} π^{-} ℓ^{+} ν_{ℓ}$ (where $ℓ = e, μ$ ) based on a sample of $20.3 fb^{- 1}$ of $e^{+} e^{-}$ annihilation…
