Poles and poltergeists in $e^{+} e^{-} \to D \bar{D}$ data

A recent report of $e^{+} e^{-} \to D \bar{D}$ events by the BESIII collaboration suggests the presence of a structure $R$ at 3900 MeV. We argue that this structure, called $G (3900)$ in the past, is not in fact due to a new $c \bar{c}$ resonance but rather naturally emerges due to a combination of interference between nearby resonances and the opening of the $D^{*} \bar{D}$ channel. We further find that the appearance of this structure does not require suppression because of a radial node in the $ψ (4040)$ wave function, although a node improves fit quality. The measured $e^{+} e^{-}$ coupling of $ψ (4040)$ is found to be substantially smaller than previously estimated. In addition, we report new corrections to the measured cross section $σ (e^{+} e^{-} \to D \bar{D})$ at energies near $ψ (3770)$ . Published by the American Physical Society2024
