On Dispersive and Nondispersive K-matrix Formalisms

Nils Hüsken, Eric S. Swanson, Adam Szczepaniak

The modeling of coupled-channel effects has become increasingly important due to the availability of highly precise data for a large variety of hadronic (re)scattering processes. T…

Poles and Poltergeists in $e^{+} e^{-} \to D D ˉ$ Data

Nils Hüsken, Richard F. Lebed, Ryan E. Mitchell +3

A recent report of $e^{+} e^{-} \to D D ˉ$ events by the BESIII Collaboration suggests the presence of a structure $R$ at 3900~MeV\@. We argue that this structure, called $G (3900)$ i…
