Non-leading corrections to the Drell-Yan cross section at small transverse momentum
The production of Drell-Yan lepton pairs at small transverse momentum is analyzed to second order in QCD perturbation theory. By calculating exactly all terms involving powers of the large logarithm ln ( Q 2 q T 2 ), we are able to confront the predictions of “soft gluon” cross sections in which the...
