Inclusive Non-Strange Meson Production and Particle Ratios in π-p Interactions at 6 GaV/c

Abstract

Inclusive production of ρ°(770), ω(783) and f(1270) has been studied in π - p interactions at 6 GeV/c. The inclusive cross sections for ρ° and f are; 2.9 ±0.3 mb and 0.47 ±0.07 mb. The semi-inclusive cross section for ω is 0.20 ±0.03 mb. These cross sections and ratios of ρ°/ π, f/ ρ° and K *+ / ρ° are compared with higher energy data. The differential cross sections for ρ°, ω and f are presented as a function of Feynman scaling variable x and squared transverse momentum P T 2 . The x distributions for ρ° and ω show them to be produced primarily in the forward direction. Inclusive ρ°, ω and f resonance production in 6 GeV/c π - p interactions seems to have not yet reached the high energy limiting behavior.
