Abstract

Abstract We present a bremsstrahlung model which at large transverse momenta p T leads to an inverse power law for the pion distribution in pp → π ±0 + X. The model predicts particle yields that increase with energy at fixed p T (breaking Feynman scaling in a definite way) and provides an understanding of the excess of π +'s over π −'s, and of the increase with p T of the associated multiplicity in the direction opposite to the observed pion; it also accounts for proton to π + ratios of order 1, but in a parameter-dependent way. The recently observed increase of the mean charged multiplicity in pp → p + MM with the transverse momentum of the projectile is also accounted for.
