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 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.
