On the basis of a parton model studied earlier we consider the production process of large mass lepton pairs from hadron-hadron inelastic collisions in the limiting region, s --coo, Q 2 /s finite, Q2and s being the squared invariant masses of the lepton pair and the two initial hadrons, respectively. General scaling properties and connections with deep inelastic electron scattering are discussed.In particular, a rapidly decreasing cross section as Q2/s -1 is predicted as a consequence of the observed rapid fall-off of the inelastic scattering structure function v W2 near threshold.
