Electro-production of high-pT hadrons

2004, Torino Aram Kotzinian 13

In the fragmentation process hadrons acquire some transverse momentum with respect to the fragmenting quark direction

Hadrons acquire also part of their transverse momentum from the intrinsic transverse momentum of the partons in the nucleon
