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 \(p_{T}^{2}\) distributions are fitted with a single exponential function at low values of \(p_{T}^{2}\) to determine the dependence of \(\langle p_{T}^{2} \rangle\) on x Bj , Q 2, W 2 and z. The z-dependence of \(\langle p_{T}^{2} \rangle\) is shown to be a potential tool to extract the average intrinsic transverse momentum squared of partons, \(\langle k_{\perp}^{2} \rangle\), as a function of x Bj and Q 2 in a leading order QCD parton model.

Notes
For these simulations, MRST2004LO PDFs in LHAPDF 5.2.2 were used; default LEPTO 6.5.1 and JETSET 7.4 settings, with the exception of LST(11)=122, which includes target mass effects and the longitudinal structure function.
