Description
In this talk I discuss the associated production of a vector or Higgs boson with a jet in hadronic collisions. When the transverse momentum of the boson-jet system is much smaller than its invariant mass, the QCD perturbative expansion is affected by large logarithmic terms that must be resummed to all orders. I discuss the all-order resummation structure of the logarithmically enhanced contributions up to next-to-leading logarithmic accuracy. The presented resummation formalism is fully differential in the kinematic variables of the boson-jet system. Soft-parton radiation produces azimuthal correlations that are fully accounted for in this framework. I present explicit analytical results up to next-to-leading order and next-to-leading logarithmic accuracy, that include the exact dependence on the jet radius. I also elaborate on the presence of non-global logarithms for this observable as well as the absence of clustering logarithms when one uses anti-kt jet-clustering.
