A detailed analysis of the inclusive production of the vector mesonsφ,K*+,0(892)$\bar K*^0 (892),\rho ^{ + ,0} ,\omega $ and the tensor mesonsK2*0)(1430) andf2(1270) inK+p interactions at 250 GeV/c is presented The data are compared with results at lower energies and with various quark-parton models. The production ofρ0,K*0(892) and$\bar K*^0 (892)$ increases at the same rate as a function ofs, is concentrated in the central region and is not reproduced by the models. Production of the tensor mesonsf2(1270) andK2*0(1340) is suppressed relative toρ0 andK*0(892) by a factor of about 3.

phi MESON INCLUSIVE PRODUCTION BY 70-GeV/c PROTONS

Antipov, Yu.M. ; Bessubov, V.A. ; Budanov, N.P. ; et al.

Phys.Lett.B 110 (1982) 326-328, 1982.

Results of the experimental study of inclusive φ meson production off berillium nuclei by 70 GeV/ c protons in the beam fragmentation region x > 0.41 are presented. Fitting of the measured differential cross sections to the forms d σ d x ∼ (1 − x) n x and d σ d p 2 t ∼ exp (−bp 2 t ) gives the parameters n = 6.0 ± 1.7 and b = (2.4 ± 0.7) (GeV/ c ) −2 . In the framework of a quark-parton model the measured φ meson x -distribution suggests that in the region of x > 0.41 nearly 90% of the φ mesons are produced via a strange sea quark fusion. The ratio of the OZI-forbidden and OZI-allowed transition coupling constants has been found to be ten times smaller than the same ratio calculated from the partial decay widths. The total inclusive cross section is estimated to be σ (pN → φ X) = (0.7 ± 0.2) × 10 −27 cm 2 .
