Abstract
The backward production of the B(1235) meson is studied in the reaction K-p →∑- π+ω . This reaction is observed in the final state ∑ -π+π+π-π0. A π+ω mass enhancement is visible in the region of the B meson for events with small |u|K-→∑-) squared four-momentum transfer. The properties of the enhancement agree with those of the B meson. The cross section for K-p→∑ -B+ at 4.15 GeV/c incident K- momentum is (3.2 ± 0.5) μ b. The backward production of the B meson is compared with similar baryon exchange productions of the A1 and C(Q1) axial vector mesons observed in the same experiment.
