Parametrisation of hadron inclusive cross sections in p-p collisions extended to very low energies

Abstract

To parametrise the inclusive differential cross sections of charged hadrons produced in p-p collisions at the CMS energy, square root s<or approximately=10 GeV, where the radial-scaling limit is not reached, a new variable xT=T*/T*max is introduced, where T* is the kinetic energy of a hadron produced in the CMS. The ratio of the low-energy inclusive differential cross section to that of its corresponding radial-scaling limit is found to be explicitly independent of pt and approaches unity monotonically and quickly from above for increasing square root s. The authors have succeeded in parametrising the inclusive differential cross sections for hadrons including pi +or-, kappa +or-, p and p, and the expressions obtained are applicable at energies from the ISR down to those near the production thresholds.
