Charge asymmetry at large pT in inelastic pp reactions at 22.4 GeV/c

Charge asymmetry in pp reactions at 22.4 GeV/c is investigated as a function of transverse momentum in the c.m. rapidity interval |y∗| < 1. The charge asymmetries in the forward and backward directions are increasing with increasing transverse momentum. The increase seems to be present both in annihilation and non-annihilation processes.
