A comparison of direct photon, $\pi^0$, and $\eta$ production in $p\bar{p}$p and $pp$ interactions at the CERN ISR

The Axial Field Spectrometer collaboration Akesson, T. ; Albrow, M.G. ; Almehed, S. ; et al.
Phys.Lett.B 158 (1985) 282-288, 1985.
Inspire Record 213984 DOI 10.17182/hepdata.30391

We have measured the production of direct photons, π 0 's, and η's in p p and pp collisions at √ s =53 GeV in the range 2≈ p T ≈6 GeV/ c for the central rapidity region | y | 0.4. No statistically significant difference between pp̄ and pp interactions is observed.

COMPARISON OF HIGH TRANSVERSE MOMENTUM PI0 PRODUCTION FROM PI-, K-, P, AND ANTI-P BEAMS.

Donaldson, G. ; Gordon, H. ; Lai, K.W. ; et al.
Phys.Rev.Lett. 40 (1978) 917-920, 1978.
Inspire Record 131684 DOI 10.17182/hepdata.14084

We compare high-transverse-momentum (P⊥) inclusive π0 production from π−, K−, p, and p¯ beams, at 100 and 200 GeV/c, for center-of-mass (c.m.) angles ranging from 2° to 115° and P⊥<4.5 GeV/c. The ratio σ(pp→π0X)σ(πp→π0X) decreases with increasing P⊥, and changes dramatically with c.m. angle. Also, the ratios σ(K−p→π0X)σ(π−p→π0X) and σ(p¯p→π0X)σ(pp→π0X) are approximately constant. These measurements are consistent with a theoretical viewpoint in which constituents of the incident hadrons undergo a hard-scattering subprocess.
