Precision diboson measurements and the interplay of pT and jet-veto resummations

Understand

In this paper we demonstrate the agreement of jet-veto resummation and pT resummation for explaining the WW cross sections at Run 1 of the LHC, and in the future.

• These two resummation techniques resum different logarithms, however via reweighting methods they can be compared for various differential or exclusive cross sections.
• We find excellent agreement between the two resummation methods for predicting the zero-jet cross section, and propose a new reweighting method for jet-veto resummation that can be used to compare other differential distributions.
• We advocate a cross-channel comparison for the high-luminosity run of the LHC as both a test of QCD and new physics.
