Inclusive production of ρ0\rho^{0} and f2f_{2} mesons in π−p\pi^{-}p interactions at 360 GeV/c

We report on a study of \u3c10 and f2 inclusive production in \u3c0 12 p interactions at 360 GeV/c, using the LEBC-EHS set-up at CERN and reconstructing about 165000 events. Thergr \u3c10, 2 and \u3c1_3^0 cross sections are determined for x_ F >0 ,x_ F >0.4 and x _F >0.6 respectively and the \u3c10 and f 2 Feynman-x distributions and transverse momentum distributions are presented

Inclusive\u3c0\ub0 production in 360 GeVpp interactions using the european hybrid spectrometer

The intermediate and forward gamma detectors of EHS are used to reconstruct π°'s produced by 360 GeV/cpp interactions in the Rapid Cycling Bubble Chamber (RCBC). Using the pp forward-backward symmetry, the inclusive π° production cross section is obtained σ <SUB>π°</SUB>=(132±11) mb. The average π° multiplicity is determined as a function of the charged particle multiplicity. The (1-x) dependence is given for different p<SUB>T</SUB> regions

Vector meson production in pi- p interactions at 360 GeV/c

The inclusive production of vector mesons (charged rho(770), omega(783), phi(1020) and neutralK *(892)) in pi\u2013 p interactions at 360 GeV/c is studied. The data are based on 160 000 reconstructed events recorded in the NA 27 Experiment using the LEBC-EHS facility at CERN. The production cross sections in the forward hemisphere in c.m.s. and the longitudinal momentum distributions are determined. The results are compared with data obtained at lower energies
