Inclusive production of π and rho0 mesons in r+p interactions at 32 GeV/c

We report and discuss experimental data on the inclusive cross sections and inclusive distributions of π+, π-, and rho0 mesons, γ rays, and rho0 mesons in π+p interactions at 32 GeV/c. The total inclusive cross sections for these particles are s(π+) = 59.7 +- 0.5 mb, s(π-) = 30.7 +- 0.4 mb, s(π0) = 38 +- 9 mb, γ) = 86.4 +- 3.5 mb, and s(rho0) = 5.9 +- 1.2 mb. Rough estimates are obtained for the cross sections for h and f mesons. The inclusive spectra are compared in detail with π+p data at other energies, with K+p, K-p, and p-barp experiments at 32 GeV/c, and with various theoretical models
