Exclusive production of ρ meson in gamma-proton collisions: dσ/dt and the role of helicity flip processes
We calculate the differential cross section dσ/dt for the diffractive photoproduction process γp→ρp and compare to recent data extracted by the CMS collaboration from ultraperipheral proton-lead collisions. Our model is based on two-gluon exchange in the nonperturbative domain. We take into account...
