Abstract

We consider the azimuthal and PT-dependence of hadrons produced in unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the factorized QCD parton model. It is shown that at small PT values, P T ≲ 1 GeV/c, lowest-order contributions, coupled to unintegrated (transverse-momentum-dependent) quark distribution and fragmentation functions, describe all data. At larger PT values, P T ≳ 1 GeV/c, the usual pQCD higher-order collinear contributions dominate. Having explained the full PT range of available data, we give new detailed predictions concerning the azimuthal and PT- dependence of hadrons which could be measured in ongoing or planned experiments by HERMES, COMPASS and JLab Collaborations.
