Competition of ${\chi }_c(2P)$ quarkonia and continuum in $e^{+}{e}^{-}\to e^{+}{e}^{-}D\bar{D}$

Izabela Babiarz, Piotr Lebiedowicz, Wolfgang Schäfer +1

We discuss the production of $D\bar{D}$ pairs in $e^{+}{e}^{-}$ collisions, where $D$ refers to either $D^0$ or $D^{+}$. The continuum mechanism with the $t/u$-channel vector-meson $D^{\ast }$…
