The simultaneous production of pion resonances and strange particles was investigated. The simultaneous production of p 0 mesons and A-K pairs was observed in events characterized by charged particle multiplicity ns = 4 and having cross sections upo = 20 ± 8 ~b. Cross sections for the production of w and YJ resonances are presented. The 1340-MeV peak in the distribution of four-pion effective masses is discussed.

Vector Meson Production in $\pi^- p$ Interactions at 360-{GeV}/$c$

The LEBC-EHS collaboration Aguilar-Benitez, M. ; Bailly, J.L. ; Batalov, A.A. ; et al.
Z.Phys.C 44 (1989) 531, 1989.
Inspire Record 278763 DOI 10.17182/hepdata.15359

The inclusive production of vector mesons (charged ρ(770), ω(783), ϕ(1020) and neutralK*(892)) in π−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.
