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

抄録

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_T². 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.
