Regge‐model predictions for K+Σ photoproduction from the nucleon

We present Regge‐model predictions for the p(λ, K+)Σ0 and n(λ, K+)Σ− differential cross sections and photon‐beam asymmetries in the resonance region. The reaction amplitude encompasses the exchange of K+(494) and K**+(892) Regge‐trajectories, introducing a mere three free parameters. These are fitted to the available p(λ, K+)Σ0 data beyond the resonance region. The n(λ, K+)Σ− amplitude is obtained from the p(λ, K+)Σ0 one through SU (2) isospin symmetry considerations.
