Backward production of a spin parity 1/sup +/ rho pi enhancement at 104 GeV

A spin-parity 1/sup +/ rho pi enhancement is observed for the 3 pi mass spectrum in the reaction K/sup -/p to Sigma /sup -/ pi /sup +/ pi /sup +/ pi /sup -/ where events with a small (K/sup -/ to Sigma /sup - /) momentum transfer are selected. The mass (1040 MeV) and width (230 MeV) of this enhancem...

description A spin-parity 1/sup +/ rho pi enhancement is observed for the 3 pi mass spectrum in the reaction K/sup -/p to Sigma /sup -/ pi /sup +/ pi /sup +/ pi /sup -/ where events with a small (K/sup -/ to Sigma /sup - /) momentum transfer are selected. The mass (1040 MeV) and width (230 MeV) of this enhancement are reminiscent of the A/sub 1/ to rho pi bump which has mainly been observed in the diffractive-like processes. The cross section for this enhancement at 4.15 GeV/c incident K/sup -/ momentum is (3.6+or-0.5) mu b. (16 refs).
