BACKWARD PRODUCTION OF A SPIN PARITY 1+RHOPI ENHANCEMENT AT 1.04 GEV
A spin-parity 1+ρ{variant}π enhancement is observed for the 3π mass spectrum in the reaction K-p → Σ-π+π+π- where events with a small (K- → Σ-) momentum transfer are selected. The mass (1040 MeV) and width (230 MeV) of this enhancement are reminiscent of the A1 → ρ{variant}π bump which has mainly be...
