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.

INCLUSIVE PRODUCTION OF THE DELTA (1232) RESONANCE IN MUON - PROTON SCATTERING AT 280-GeV/c

The European Muon collaboration Arneodo, M. ; Arvidson, A. ; Aubert, J.J. ; et al.
Nucl.Phys.B 264 (1986) 739-751, 1986.
Inspire Record 218464 DOI 10.17182/hepdata.33712

Inclusive production of the Δ (1232) resonance has been measured in 280 GeV/ c muon-proton interactions. The production of the Δ ++ as a function of the variables χ BJ , W , Q 2 , χ F and p T 2 is investigated. The average Δ ++ multiplicity is found to be smaller, by a factor of 6.2 ± 1.2, than the average multiplicity of protons. An upper limit for Δ 0 production is obtained. The net hadronic charge distribution for events with a Δ ++ is presented. The results are compared to the predictions of the Lund and Fire string models.

Inclusive Production of Lambdas and Anti-lambdas in $\gamma p$ Interactions for Photon Energies Between 25-{GeV} and 70-{GeV}

The Bonn-CERN-Ecole Poly-Glasgow-Lancaster-Manchester-Orsay-Paris-Rutherford-Sheffield collaboration Aston, D. ; Atkinson, M. ; Bailey, R. ; et al.
Nucl.Phys.B 195 (1982) 189-202, 1982.
Inspire Record 167734 DOI 10.17182/hepdata.34176

Results are presented on the inclusive photoproduction of λ and λ for incident photon energies between 25 and 70 GeV. The slope parameter of the p T 2 distribution is found to be 2.83±0.1 GeV −2 for λ and 3.28±0.25 GeV −2 for λ . The x F distributions, measured in the range −0.2 to 0.7, show that while λ are produced centrally, λ production extends to more negative values of x F ; the shapes show no energy dependence and are similar to those in pion-induced reactions. The polarization of the produced λ is less than 10%. The results are discussed in terms of vector dominance and quark fusion models.

Inclusive Production of Y* Resonances in K- p Interactions at 14.3-GeV/c

Bardadin-Otwinowska, M. ; Barloutaud, R. ; Borg, A. ; et al.
Nucl.Phys.B 98 (1975) 418-428, 1975.
Inspire Record 99415 DOI 10.17182/hepdata.31900

The inclusive production of Σ + (1385), Σ − (1385), Λ (1405) and Λ (1523) in K − p interactions at 14.3 GeV/ c is studied. Cross sections are presented and the x dependence of the invariant cross sections is discussed. The density matrices for production of the spin- 3 2 resonances at small momentum transfer to the target are consistent with spin-0 exchange.

Production of gamma rays in K- p and K+ p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Beilliere, P. ; Cochet, Christian ; Dumont, J J ; et al.
Nucl.Phys.B 91 (1975) 219-231, 1975.
Inspire Record 2852 DOI 10.17182/hepdata.6709

Inclusive cross sections and longitudinal momentum distributions are presented for γ rays produced in K − p and K + p interactions at 32 GeV/c in the 4.5 m Mirabelle hydrogen bubble chamber at the Serpukhov accelerator. The average longitudinal and transverse momentum of neutral pions and the average π 0 multiplicity ▪ 〈 n π 0〉 are estimated. It is found that 〈 n π 0〉 is an increasing function of the number of charged prongs.
