Revisiting gauge invariance and Reggeization of pion exchange

Gloria Montana, Daniel Winney, Lukasz Bibrzycki +10

The Reggeized pion is expected to provide the main contribution to the forward cross section in light meson photoproduction reactions with charge exchange at high energies. We disc…

Studying $π^{+} π^{-}$ photoproduction beyond Pomeron exchange

Łukasz Bibrzycki, Nadine Hammoud, Vincent Mathieu +10

Forward photoproduction of $π^{+} π^{-}$ pairs with invariant mass of the order of $m_{ρ} \sim 770$ MeV is traditionally understood to be produced via Pomeron exchange. Based on a detailed…

Studying the production mechanisms of light meson resonances in two-pion photoproduction

Łukasz Bibrzycki, Nadine Hammoud, Vincent Mathieu +2

A theoretical model of two-pion photoproduction is presented. The model encodes the prominent $ρ (770)$ resonance and the expected leading background contribution coming from the De…
