The transverse momentum profile of a quark jet

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The first and second moments of the transverse momentum distribution of pions ine + e −-annihilation at fixed longitudinal momentum with respect to the jet axis are discussed, treating the hadronic final state evolving from the 2-quark system in the framework of a fireball-model. Good agreement with the published data is found. A comparison with thep T -distribution of electroproduction is made, showing qualitative agreement. This casts serious doubts on previous conclusions favoring a large partonk T inside the proton.
