Gauge invariance, parton transverse momenta, and single-lepton spectra at high transverse momentum

Journal Article · · Phys. Rev., D; (United States)
We discuss minimal extensions of the Drell--Yan process to low Q/sup 2/, incorporating gauge invariance and transverse-momentum fluctuations of the partons. Resulting predictions for single-lepton cross sections at high P/sub T/ and for lepton pair production at low Q/sup 2/ are discussed. Existing single-lepton spectra with P/sub T/ < 5 GeV/c are not explained by these extensions of the Drell--Yan process, but for P/sub T/ > 5 GeV/c the Drell--Yan mechanism will probably dominate.
