Inclusive Production of Anti-xi+ and $\Xi^-$ in $K^+ p$ Interactions at 32-{GeV}/c

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Chliapnikov, P.V. ; et al.
Nucl.Phys.B 176 (1980) 51, 1980.
Inspire Record 153556 DOI 10.17182/hepdata.11096

The inclusive production of Ξ + and Ξ − hyperons is investigated in K + p interactions at 32 GeV/ c . The production cross sections, 36.4±9 μ b for the Ξ + and 6.5±3 μ b for the Ξ − , are rising strongly with energy similarly to Λ and Λ production in K + p interactions. The Ξ + are produced preferentially in the forward direction in the c.m.s., while the Ξ − are produced dominantly backwards. The average transverse momenta 〈p T 〉 Ξ + =0.73±0.09 GeV /c and 〈 p T 〉 Ξ − =0.58±0.09 GeV/ c .

INCLUSIVE AND SEMIINCLUSIVE PRODUCTION OF POSITIVE PIONS AND PROTONS IN ANTI-P P INTERACTIONS AT 22.4-GEV/C

Nucl.Phys.B 174 (1980) 45-67, 1980.
Inspire Record 159212 DOI 10.17182/hepdata.7929

New results on the inclusive and semi-inclusive production of π + mesons and protons in the whole phase space are given for about 2.2 · 10 4 inelastic p p interactions at 22.4 GeV/ c . A method of statistical separation for spectra of particles of the same charge which are produced in CP -symmetrical reactions is discussed in detail. Experimental data are compared with quark-parton model predictions.

Characteristics of J/$\psi$ and $\Upsilon$ production at the {CERN} intersecting storage rings

Phys.Lett.B 91 (1980) 481-486, 1980.
Inspire Record 152744 DOI 10.17182/hepdata.27235

We present the B( d θ d y ) y=0 for J /ψ over thefull range of ISR energies and for ϒ at √ s = 53 and 63 GeV, using their dielectron decay mode. The average transverse momentum and the decay angles are presented. We found ( p T ) = 1.75 ± 0.19 GeV for ϒ, being higher than ( p T ) of the continuum and rising with √s. We present a comparison of the cross sections of J/ψ and ϒ with those of the continuum, at the same masses, as a function of √s. An appropriate scaling of the hadronic production of quark-antiquark narrow bound states involving ⋉, J/ψ, ψ′, ϒ, and ϒ′ is presented as a function of m /√ s at y = 0, and is compared with Drell-Yan scaling.

Data from a study of electron pairs produced in pp collisions (√ s = 5 and 63 GeV) are used to extend measurements of the scaling function down to m /√ s ≈ 0.07 (4.5 < m < 19 GeV). The dilepton continuum can be described by the scaling formula (fx475-1)

A Measurement of Direct Photon Production at Large P(T) at the {CERN} {ISR}

Diakonou, M. ; Kourkoumelis, C. ; Resvanis, L.K. ; et al.
Phys.Lett.B 91 (1980) 296-300, 1980.
Inspire Record 152520 DOI 10.17182/hepdata.27234

We have measured direct photon production in pp collisions at the CERN intersecting storage rings for c.m. energies 31 < √ s < 63 GeV and transverse momenta up to 9GeV/ c , using segmented lead/liquid-argon calorimeters. The ratio of direct photon to π 0 production is significantly larger than zero, starting at p T ≈ 4 GeV/ c and increasing to values of about 0.4 at 9GeV/ c . No significant √s dependence is seen.
