Production of direct photons and neutral mesons at large transverse momenta by pi- and p beams at 500-GeV/c

The FERMILAB-E706 collaboration Alverson, G. ; Baker, W.F. ; Ballocchi, G. ; et al.
Phys.Rev.D 48 (1993) 5-28, 1993.
Inspire Record 353153 DOI 10.17182/hepdata.22583

We present results from the initial run of Fermilab experiment E706. The data include incident π− and p beams at 500 GeV/c on Be and Cu targets, and span the kinematic ranges of transverse momentum and rapidity of 3.5≤pT≤10 GeV/c and −0.7≤yc.m.≤0.7, respectively. We have measured cross sections for π0 and direct-photon production, as well as the ηπ0 production ratio. From the data on Be and Cu, we have extracted the nuclear dependence of π0 production, parametrized as Aα. The cross sections are compared with next-to-leading-log QCD predictions for different choices of the QCD momentum scales and several sets of parton distribution functions.

A Search for Direct Photon Production in 200 GeV/c and 300 GeV/c Proton - Beryllium Interactions

Baltrusaitis, R.M. ; Binkley, Morris E. ; Cox, B. ; et al.
Phys.Lett.B 88 (1979) 372-378, 1979.
Inspire Record 142314 DOI 10.17182/hepdata.27292

A search has been made for direct photon production in pBe interactions at 200 and 300 GeV/ c over the kinematic region 1.5 < P ⊥ < 4.0 GeV/ c and −0.7 < X F < 0 (90° < θ cms < 160°). An excess of single photons above that which is predicted from the measured π 0 and η 0 production is observed. Theratio of γ / π 0 production is calculated assuming that the excess arises from direct photon production. We find that this ratio averages 0.070 ± 0.025 (including systematic errors) in this region of X F and P ⊥ for our 200 and 300 GeV/ c data. We have used our measured value of the η / π 0 ratio of 0.47 ± 0.10 in the determination of the γ / π 0 ratio. The variation of γ / π 0 with X F , P ⊥ , X R and θ cms presented.

Inclusive High $p_T \pi^0$ Production From $\pi^\pm$ and Protons at 200-{GeV}/$c$

The NA3 collaboration Badier, J. ; Bardadin-Otwinowska, M. ; Bemporad, C. ; et al.
Z.Phys.C 30 (1986) 45, 1986.
Inspire Record 216588 DOI 10.17182/hepdata.15912

We have measured the inclusive cross-section for π0 production at large transverse momentum by 200 GeV/c positive and negative hadron beams on Carbon targets (2.9<PT<6 GeV/c; −0.4<y*<1.2). We used the NA3 spectrometer at the CERNSPS.
