Meson Resonance Production in p p Interactions at 53-GeV (Center-of-Mass) Energy

Boehm, A. ; VanDalen, Gordon J. ; Kernan, A. ; et al.
Phys.Rev.Lett. 41 (1978) 1761-1764, 1978.
Inspire Record 136909 DOI 10.17182/hepdata.3338

At the CERN intersecting storage ring the inclusive differential cross section [dσdσ]y=1 has been measured for f0, g0, K*0(1420), and K¯*0(1420) production: We obtain 0.58±0.05 mb, 0.09±0.05 mb, 38±15 μb, and 26±13 μb, respectively. The corresponding total inclusive cross sections are estimated to be 2.62±0.26 mb, 0.40±0.22 mb, 154±60 μb, and 107±52 μb, respectively. The magnitude of the K* cross section implies a cross section of approximately 5 μb for production of a charmed DD¯ pair.

Suzuki, A. ; Fukawa, M. ; Kabe, S. ; et al.

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.

Production of Vector and Tensor Mesons in Proton Proton Collisions at $\sqrt{s}=52$.5-{GeV}

Inclusive production of ϱ0,f, andg0 mesons and ofKs0,K*0 (892), ϕ andK*0(1430)mesons has been measured at <y>∼2.6 and <pT>∼1.1 GeV/c in proton-proton interactions at\(\sqrt s= 52.5\) GeV. The negative particle from the two-body decays of these resonances were identified by a threshold Cerenkov counter and used for triggering. Starting from the measured differential cross section, total inclusive cross sections for the vector and tensor mesons were determined using various parametrizations for they andpT dependence of the differential cross section. The experimental results are discussed in the framework of production models based on the parton picture. The strangeness suppresion factor λ=(0.30±0.10) due toSU(3) symmetry breaking of the quark sea is derived.
