In this extended analysis using the ZEUS detector at HERA, the photoproduction of isolated photons together with a jet is measured for different ranges of the fractional photon energy, $x_\gamma^{\mathrm{meas}}$, contributing to the photon-jet final state. Cross sections are evaluated in the photon transverse-energy and pseudorapidity ranges $6 < E_T^{\gamma} < 15$ GeV and $-0.7 < \eta^{\gamma} < 0.9$, and for jet transverse-energy and pseudorapidity ranges $4 < E_T^{\rm jet} < 35$ GeV and $-1.5 < \eta^{\rm jet} < 1.8$, for an integrated luminosity of 374 $\mathrm{pb}^{-1}$. The kinematic observables studied comprise the transverse energy and pseudorapidity of the photon and the jet, the azimuthal difference between them, the fraction of proton energy taking part in the interaction, and the difference between the pseudorapidities of the photon and the jet. Higher-order theoretical calculations are compared to the results.

CHARGED PARTICLE MULTIPLICITIES IN PI-, K- AND ANTI-P INTERACTIONS WITH NUCLEI AT 40-GEV/C

Inspire Record 214970 DOI 10.17182/hepdata.22350

Interactions of 40 GeV/c πp-,K− and\(\bar p\) on Li, C, S, Cu, CsI and Pb were studied with the RISK-streamer chamber spectrometer. We present multiplicities of negatively charged particles, as well as of protons, and the correlations between them. The normalized mean multiplicity of negative particles,R−, depends on\(\bar v\), the average number of inelastic collisions as\(R^ -= (0.73 \pm 0.04) + (0.34 \pm 0.02)\bar v\). The dependence of the normalized dispersion of negative particles,D−/, on the number of protons favours independent collision models and contradicts the coherent tube picture. The excess of fast positive particles behaves asA0.4 and shows, for the heavier nuclei, a clear correlation with identified protons.

Inclusive and Semiinclusive Two Pion Correlations in p p Collisions at 69-GeV/c

Inspire Record 99995 DOI 10.17182/hepdata.8917

Correlations between pions produced in pp collisions at 69 GeV/c are observed both for π−π+ and π−π−. Short-range correlations in rapidity are present fory1⋍y2 in both cases; an enhancement is seen aroundy1=y2=±1. Correlations between transverse variables are linked to those in rapidity for π−π− combinations, whereas the effect is essentially kinematical for π+π−.

INVARIANT CROSS-SECTIONS FOR THE INCLUSIVE REACTIONS anti-p p ---> pi+ X AND anti-p p ---> p X AT 22.4-GeV/c

Inspire Record 130221 DOI 10.17182/hepdata.37561

Invariant inclusive cross-sections for π+-mesons and protons from\(\bar pp\) reactions at 22.4 GeV/c are presented. The average multiplicity for the production of π+-mesons is 1.92±0.02 and for protons 0.41±0.02. Annihilation spectra have been approximated by using the difference between\(\bar pp\) and pp data. The resulting distributions have similar gross features as the total\(\bar pp\) data.
