Measurement of Dimuon Production at the {ISR}

Antreasyan, D. ; Atwood, W. ; Battiston, R. ; et al.
Phys.Rev.Lett. 45 (1980) 863, 1980.
Inspire Record 153857 DOI 10.17182/hepdata.20656

Prompt dimuon production has been measured. Events with mass up to 25 GeV/c2 are observed, as well as the J and ϒ resonances. Cross sections are given for J and ϒ production. For the continuum, the scaling function F(τ) is measured at very small values of τ=ms covering the range 0.05<τ<0.20.

ANGULAR DEPENDENCE OF HIGH P(T) pi0 PRODUCTION

Lloyd Owen, D. ; Abshire, G.W. ; Finocchiaro, G. ; et al.
Phys.Rev.Lett. 45 (1980) 89, 1980.
Inspire Record 153201 DOI 10.17182/hepdata.20655

The π0 inclusive cross section for c.m. production angles θ=90° and 22°>~θ>~5° at c.m. energies of s=23 and 53 GeV has been measured. This cross section is strongly dependent on both θ and s at small angles. The hypothesis of radial scaling is shown to be incapable of incorporating both θ and s dependence of the cross section. A recent quantum-chromodynamics calculation is in qualitative agreement with our results.

Direct Photon Production at the $\psi$

Scharre, D.L. ; Alam, M.S. ; Boyarski, A. ; et al.
Phys.Rev.D 23 (1981) 43, 1981.
Inspire Record 153865 DOI 10.17182/hepdata.24079

We present results of a detailed analysis of inclusive direct photon production at the ψ(3095). The direct-photon momentum distribution for x>0.4 is presented and compared with the leading-order quantum-chromodynamic prediction. The total production rate is found to be consistent with theoretical expectations, but the observed momentum distribution is considerably softer. Results of an analysis of some inclusive properties of the hadronic system recoiling against the direct photon are presented. The mean charged-particle and Ks multiplicities are presented as functions of the invariant mass of the hadronic system. These data agree well with the corresponding mean multiplicities measured in e+e− annihilations at center-of-mass energies comparable to the invariant mass of the hadronic system.

Charged Pion, Kaon, Proton and anti-Proton Production in High-Energy e+ e- Annihilation

The TASSO collaboration Brandelik, R. ; Braunschweig, W. ; Gather, K. ; et al.
Phys.Lett.B 94 (1980) 444-449, 1980.
Inspire Record 153656 DOI 10.17182/hepdata.27192

Production of pions, kaons, protons and antiprotons has been studied in e + e − annihilations at 12 and 30 GeV centre of mass energy using time of flight techniques. The fractional yield of charged kaons and baryons appears to rise with outgoing particle momentum. At our highest energy at least 40% of e + e − annihilations into hadrons are estimated to contain baryons.

The Energy Dependence of Charged Particle Multiplicity in $p p$ Interactions

Basile, M. ; Cara Romeo, G. ; Cifarelli, L. ; et al.
Phys.Lett.B 95 (1980) 311-312, 1980.
Inspire Record 153920 DOI 10.17182/hepdata.27162

The average charged multiplicity in proton-proton interactions has been studied at √ s = 62 GeV. A very good agreement with the average charged multiplicity measured in e + e − annihilation at different energies is obtained by redefining, in p-p, the correct energies available for particle production. This means that a p-p collision at √ s = 62 GeV does in fact correspond to a large range of effective hadronic energies available for particle production.

Measurements of the Total $\pi$ He and $p$ He Cross-sections and the Slopes of the Forward Diffraction Peak at Energies From 50-{GeV} to 300-{GeV}

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.
Nucl.Phys.B 187 (1981) 205, 1981.
Inspire Record 154079 DOI 10.17182/hepdata.34264

Differential cross sections for elastic scattering of pions and protons on helium have been measured at incident momenta ranging from 50 to 300 GeV/ c in the t -range 0.008 < | < | < 0.05 (GeV/ c ) 2 . Both recoil α-particles and forward particles were detected in this experiment. The experimental method provided an absolute normalization of the cross sections with an estimated precision of 1%. From the analysis of the data, the diffraction slope parameters and total cross sections have been obtained. The results are compared with Glauber model calculations.

High Mass Meson Resonance Production in $p p$ Interactions at 405-{GeV}/$c$

Suzuki, A. ; Fukawa, M. ; Kabe, S. ; et al.
Nucl.Phys.B 172 (1980) 327-334, 1980.
Inspire Record 153967 DOI 10.17182/hepdata.34484

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.
