Description
We present a formalism for the systematic resummation of a class of logarithms relevant for jet observables in QCD. The logarithms are associated with the rapidities of factorized partons (which are either soft or collinear to specified directions) diverging under certain phase space constraints. The resummation is necessary for a consistent formulation of the perturbation series, and cannot be captured by standard renormalization group techniques. The formalism allows for a consistent merging of resummed corrections with the low energy matrix elements, with full control of the errors in the resummation scheme. Applications to the jet broadening observable and the Higgs transverse momentum cross-sections are outlined.
