  "abstract": "Using the quantum field theory, we derive a Breit-Wigner-type formula for the $e^+ e^-$ annihilation into a vector meson and its antiparticle, and relate the formula parameters to observable quantities. The formula's soundness is checked by fitting the $e^+ e^- \\to D^{\\ast+}D^{\\ast-}$ data published by the BESIII Collaboration in 2022.",
