The production of neutral pions by the interaction of 200A·GeV p and16O projectiles with a Au target has been studied in the pseudorapidity range 1.5≦η≦2.1. Transverse momentum spectra have been measured between 0.4 GeV/c and 3.6 GeV/c and their dependence on the centrality of the collision has been investigated. The peripheral-collision spectra display a marked change of slope with a hard component starting at about 1.8 GeV/c, in contrast to central-collision data. The data are discussed in comparison to p+p and α+α data from the ISR.

Photon and Neutral Pion Distributions in 60-agev and 200-agev $^{16}$O + Nucleus and Proton + Nucleus Reactions

The WA80 collaboration Albrecht, R. ; Awes, T.C. ; Baktash, C. ; et al.
Phys.Lett.B 201 (1988) 390-396, 1988.
Inspire Record 264256 DOI 10.17182/hepdata.29992

Transverse momentum ( p T ) distributions of inclusive photons and neutral pions at midrapidity are measured with a lead glass calorimeter in 60 and 200 A GeV 16 O + nucleus and proton + nucleus reactions . The variation of the average transverse momentum is investigated as function of centrality, determined by measurements of the remaining energy of the projectile and the charged particle multiplicity. For small values of the entropy, deduced from the multiplicity density, an increase in average p T is observed levelling off for larger values of entropy. The target-mass and energy dependence of π 0 p T distributions are presented.

Forward and Transverse Energy Distributions in Oxygen Induced Reactions at 60-agev and 200-agev

The WA80 collaboration Albrecht, R. ; Awes, T.C. ; Baktash, C. ; et al.
Phys.Lett.B 199 (1987) 297-303, 1987.
Inspire Record 254598 DOI 10.17182/hepdata.30059

Results are presented from reactions of 60 A GeV and 200 A GeV 16 O projectiles with C, Cu, Ag, and Au nuclei. Energy spectra measured at zero degrees and transverse energy distributions in the pseudorapidity range from 2.4 to 5.5 are shown. The average transverse energy per participant is found to be nearly independent of target mass. Estimates of nuclear stopping and of attained energy densities are made.
