Study of the reactions γp → K+ Σ± π∓ at photon energies up to 2.6 GeV
The reactions γp → K+ Σ± π∓ were studied with the SAPHIR detector using a tagged photon beam at the electron stretcher facility ELSA in Bonn. The decays Σ− → nπ− and Σ+ → nπ+, pπ0 were fully reconstructed. Reaction cross-sections were measured as a function of the photon energy from threshold up to 2.6 GeV with considerably improved statistics compared to a previous bubble chamber measurement. The cross-sections rise monotonically with increasing photon energy. The two-particle mass distributions of Σ±π∓ and K+π− show substantial production of resonant states.
