A measurement of inclusive pi$^{0}$ production at large p$_{T}$ from pp collisions at the CERN ISR

The inclusive cross section for large p/sub T/ pi /sup 0/ production near 90 degrees 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 p/sub T//sup -n/F(x/sub T/), with constant n or with n allowed t...

Descripción
Sumario:The inclusive cross section for large p/sub T/ pi /sup 0/ production near 90 degrees 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 p/sub T//sup -n/F(x/sub T/), with constant n or with n allowed to depend on x/sub T/=2p/sub T// square root s. For square root s=53.1 and 62.4 GeV, the value of n found for 3.5<p/sub T/<7.0 GeV/c is n=8.0+or-0.5, in agreement with previous experiments. However, for 7.5<p/sub T/<14.0 GeV/c the value becomes n=5.1+or-0.4. (20 refs).
