Vector boson production in joint resummation
Journal of High Energy Physics, 2017 We study the transverse momentum (QT) distribution of an electro-weak vector boson produced via the Drell-Yan mechanism, in the context of joint resummation.

Combined threshold and transverse momentum resummation for inclusive observables [PDF]
Journal of High Energy Physics, 2017 We present a combined resummation for the transverse momentum distribution of a colorless final state in perturbative QCD, expressed as a function of transverse momentum pT and the scaling variable x.

Bootstrapping Rapidity Anomalous Dimensions for Transverse-Momentum Resummation [PDF]
Physical Review Letters, 2017 A soft function relevant for transverse-momentum resummation for Drell-Yan or Higgs production at hadron colliders is computed through to three loops in the expansion of strong coupling, with the help of the bootstrap technique and supersymmetric ...

Resummation of electroweak Sudakov logarithms for real radiation [PDF]
Journal of High Energy Physics, 2016 Using the known resummation of virtual corrections together with knowledge of the leading-log structure of real radiation in a parton shower, we derive analytic expressions for the resummed real radiation after they have been integrated over all of phase

AbstractResummation methods can significantly improve the accuracy of ab initio electronic structure computations without increasing the computational cost. For perturbation theories, resummation methods can be designed by constructing approximants to model the known singularity structure of the theory in the complex plane of the perturbation parameter.

The basic methods of perturbative quantum chromodynamics are introduced and developed through an analysis of short- and long-time dependence in time-ordered perturbation theory for quantum fields. Jet cross sections are shown to be dominated by short times, and hence to be infrared safe.
