Title: New approach to lepton pair production. [Thermal parton model]

Abstract

Arguments are first presented to suggest that perturbative QCD calculations cannot account for the average transverse momentum of the dileptons observed in hadronic collisions at present energies. Regarding the complication as being due to the many gluon interactions in the initial state, a thermal parton model is considered which is a combination of the thermodynamical model and the usual parton model. With practically no free parameter the observed features of can be reproduced with the correct dependences on the incident energy and the mass and rapidity of the dileptons.
