We predict the triple differential cross section of the Drell-Yan process pp{yields}l{sup +}l{sup -}X in the kinematical regimes relevant for the upcoming PANDA experiment, using a model that accounts for quark virtuality as well as primordial transverse momentum. We find a cross section magnitude of up to 10 nb in the low mass region. A measurement with 10% accuracy is desirable in order to constrain the partonic transverse momentum dispersion and the spectral function width within {+-}50 MeV and to study their evolution with M and {radical}(s)
