Description

The inclusive cross section for large psub(T) π0 production near 900 in p-p collisions at the CERN ISR is presented for centre-of-mass energies 30.7, 53.1 and 62.4 GeV. The data are inconsistent with scaling of the form psup(-n)sub(T)F(xsub(T)), with constant n or with n allowed to depend on xsub(T)=2psub(T)/√s. For √s=53.1 and 62.4 GeV, the value of n found for 3.5<psub(T)<7.0 GeV/c is n=8.0+-0.5, in agreement with previous experiments. However, for 7.5<psub(T)<14.0 GeV/c the value becomes n=5.1+-0.4.
