  We calculate the q q correlation function associated to transverse target
lepton-nucleon inclusive deep-inelastic scattering by direct evaluation of the
corresponding matrix element. We use the electromagnetic impact parameter
potential for a transversely polarized nucleon to define the q q correlation
function for each avor in terms of the field components of that avor. The
results are compared with the two existing models for the q q correlator. Using
the calculated q q correlation function, we estimated the transverse target SSA
in IDIS process.
