Vetoes on energetic jets are common in experimental analyses and are used to reject backgrounds which have similar final states to signal processes of interest. In placing a jet veto, however, one introduces large logarithms of the veto scale over the hard scale of the process. I will discuss how the resummation of these logarithms in a SCET approach can be embedded into Monte Carlo event...
In this talk I will present the resummation of one-jettiness up to N$^3$LL accuracy for the Z+jet production process at the LHC. The resummed calculation is matched to the corresponding fixed-order predictions extending the validity of the results to regions of the phase space where further hard emissions are present. I will show numerical results and discuss the convergence of the different...
