Improving Higgs predictions with resummation

Experimental analyses often use jet binning to distinguish between different kinematic regimes and separate contributions from background processes. To accurately model theoretical uncertainties in these measurements, a consistent description of the jet bins is required. We present a complete framework for the combination of resummed results for production processes in different exclusive jet bins, focusing on Higgs production in gluon fusion as an example. We estimate that the relevant theoretical uncertainties on the signal strength in the H → WW^∗ analysis are reduced by nearly a factor of 2 compared to the current value using our methodology.
