Threshold resummation for electroweak annihilation from DIS data

We show that higher-order coefficients required to perform threshold resummation for electroweak annihilation processes, such as Drell-Yan or Higgs production via gluon fusion, can be computed using perturbative results derived in deep inelastic scattering. As an example, we compute the three-loop coefficient D-(3), generating most of the fourth tower of threshold logarithms for the Drell-Yan cross section in the MS-scheme, using the recent three-loop results for splitting functions and for the quark form factor, as well as a class of exponentiating two-loop contributions to the Drell-Yan process.
