Description
The WW production cross-section measured at the LHC has been consistently exhibiting a mild excess beyond the SM prediction leading to speculations that new physics could be hiding in these measurements. In this talk, I discuss a possible explanation of the excess in terms of large logarithms that arise from a jet-veto condition that is imposed in the experimental analyses to reduce backgrounds. Resummation of these logarithms is performed analytically by employing soft collinear effective theory, and the results are compared with the Monte Carlo predictions. Resummation of terms associated with complex values of scales is also considered providing a more reliable method of estimating scale uncertainties.
