Abstract

Multiplicities of charged hadrons produced in deep inelastic muon scattering off a ⁶LiD target have been measured as a function of the DIS variables x _Bj , Q ², W ² and the final state hadron variables p _T and z. The distributions are fitted with a single exponential function at low values of to determine the dependence of on x _Bj , Q ², W ² and z. The z-dependence of is shown to be a potential tool to extract the average intrinsic transverse momentum squared of partons, , as a function of x _Bj and Q ² in a leading order QCD parton model.
