Universality of the Collins-Soper-Sterman nonperturbative function in vector boson production

  title={Universality of the Collins-Soper-Sterman nonperturbative function in vector boson production},
  author={Anton V. Konychev and Pavel M. Nadolsky},
We revise the b∗ model for the Collins-Soper-Sterman resummed form factor to improve description of the leading-power contribution at nearly nonperturbative impact parameters. This revision leads to excellent agreement of the transverse momentum resummation with the data in a global analysis of Drell-Yan lepton pair and Z boson production. The nonperturbative contributions are found to follow universal quasi-linear dependence on the logarithm of the heavy boson invariant mass, which closely… CONTINUE READING
