Photoproduction of π + π − pairs in a model with tensor-pomeron and vector-odderon exchange
Photoproduction of π + π − pairs in a model with tensor-pomeron and vector-odderon exchange
We consider the reaction (gamma p) to (pi+ pi- p) at high energies. Our description includes dipion production via the resonances rho, omega, rho-prime and f2, and via non-resonant mechanisms. The calculation is based on a model of high energy scattering with the exchanges of photon, pomeron, odderon and reggeons. …
