Lagrangian-based model of the $e^{+} e^{-} \to V V ˉ$ process applied to the $e^{+} e^{-} \to D^{+} D^{-}$ data

Peter Lichard

The paper derives a Breit‑Wigner‑type formula for electron‑positron annihilation into a vector meson and its antiparticle using quantum field theory, and validates it by fitting re…
