ON THE SCALING OF INCLUSIVE SPECTRA OF SECONDARY PIONS IN THE FORWARD REGION

Abstract

Using available collider data the Feynman scaling on inclusive spectra of secondary pions is critically examined in the forward and very forward region incorporating the seagull effect. It is found that scaling holds to 10–15% in the forward region at least up to the center-of-mass energy 900 GeV. It is further observed that the Wdowczyk–Wolfendale scale breaking model is satisfied in the forward region only when inelasticity into pions decreases with energy.
