High mass meson resonance production in pp interactions at 405 GeV/c

Abstract We have observed high mass resonances with mass above 1.5 GeV in pp interactions at 405 GeV/ c . We obtain cross sections 13.2 ± 2.9, 5.1 ± 2.0, 2.5 ± 1.5 and 0.27 ± 0.18 mb for ϱ 0 , f, g 0 , and h meson production, respectively. The invariant x and p T 2 distributions for produced resonances are analysed. A relative comparison of the average 〈 p T 〉 distribution as a function of resonance masses with that for μ + μ − pair production shows remarkable similarity.

n interactions at 3.0, 3.5, 4.0 and 4.5 GeV/c are studied. Cross sections ofKs0, Ks0Ks0 andK*±(892) are presented for each incident momentum. The production ofKs0 andK*±(892) through annihilation process is investigated. It is found that the annihilation process is dominant but decreases with incident momentum. The annihilation process is compared withe+e− interactions. Remarkable similarity between them is found in then
