Production of pi0 and eta mesons at large transverse momenta in pp and p Be interactions at 530-GeV/c and 800-GeV/c

We present results on the production of high transverse momentum pizero and eta mesons in pp and pBe interactions at 530 and 800 GeV/c. The data span the kinematic ranges: 1 < p_T < 10 GeV/c in transverse momentum and 1.5 units in rapidity. The inclusive pizero cross sections are compared with next-to-leading order QCD calculations and to expectations based on a phenomenological parton-k_T model.

Production of High Transverse Momentum Prompt Photons and Neutral Pions in Proton Proton Interactions at 280-GeV/c

The WA70 collaboration Bonesini, M. ; Bonvin, E. ; Booth, P.S.L. ; et al.
Z.Phys.C 38 (1988) 371, 1988.
Inspire Record 252633 DOI 10.17182/hepdata.15647

The inclusive cross sections for production of prompt photons and π0s by 280 GeV/c protons incident on a liquid hydrogen target, have been measured forpT in the range 4.0 to 6.5 GeV/c and for |xF|<0.45. A quantitative comparison of the prompt photon cross section with next-to-leading order QCD predictions using Duke and Owens structure functions is performed. Phenomenological fits to the π0 and prompt photon cross sections are given.

A Measurement of $\pi^0$ Production at Large Transverse Momentum in $\pi^- p$, $\pi^+ p$ and $p p$ Collisions at 300-{GeV}/$c$

The NA24 collaboration De Marzo, C. ; De Palma, M. ; Favuzzi, C. ; et al.
Phys.Rev.D 36 (1987) 16, 1987.
Inspire Record 236249 DOI 10.17182/hepdata.23354

Cross sections for inclusive π0 production at large transverse momentum pT were measured in π−p, π+p, and pp collisions at 300 GeV/c. The cross-section ratio σ(π−p→π0X)/σ(π+p→π0X) was found to be consistent with unity in the pT region of 1 to 5 GeV/c. The cross-section ratio σ(π+p→π0X)/σ(pp→π0X) however is growing with increasing pT and increasing π0 c.m.-system rapidity in agreement with parton-model expectations, where the partons in the pions have on average higher momenta than in the proton.
