Abstract

We have measured the production of one and two large transverse momentum hadrons in pp and pp interactions in the range 2 < pT < 6 GeV/c for the central rapidity region |y| < 0.9 at s = 63 and 31 GeV. No statistically significant difference between pp and pp collisions is observed. The results are in accordance with lowest order QCS perturbative calculations and rule out a large contribution of Constituent Interchange Model (CIM), di-quark of quark-fusion subprocesses in this kinematic range.
