A possible origin of the large e/ pi ratio at low p/sub T/ in hadronic collisions at high energy

It is suggested that the increase of the e/ pi ratio at low transverse momenta in hadronic collisions is caused by the subprocesses like QQ to e/sup +/e/sup -/+X of quarks and antiquarks created during the space-time evolution of the collision. As a model of such process the authors calculate QQ to...

description It is suggested that the increase of the e/ pi ratio at low transverse momenta in hadronic collisions is caused by the subprocesses like QQ to e/sup +/e/sup -/+X of quarks and antiquarks created during the space-time evolution of the collision. As a model of such process the authors calculate QQ to e/sup +/e/sup -/+ 'gluon'. The p/sub T/ spectra of single leptons and mass spectra of dileptons following from this model are estimated and compared with the data. (16 refs).
