t-channel factorization description of γγ→V 1 V 2

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

At-channel factorization model is used to estimate cross sections for the processes γγ→V 1 V 2. WheneverV=ρ, the width of the ρ has been included in the calculations. The channels γγ→ρ0ρ0, ρ0ϕ, ϕϕ, ωω, ρ0ω and ρ+ρ are calculated for two quasi-real photons. Predictions are also given for the process γ*γ→ρ0ρ0 for virtual photon mass squaredQ 2<5 GeV2. Our results are consistent with all available experimental data.
