Description

In the absence of new particles at the LHC, the effective field theory framework is appropriated to look for small deviations from the Standard Model (SM). In this case, the leading effect is encoded on the interference term between the SM and dimension-6 operators. However, at the high energy limit due to helicity selection rules, this term, for some operators, is suppressed which leads to an obstacle to probe new physics. In this work, we exploit the resurrection of this suppressed interference term unfolding the angular distribution in the diboson production. The unfolding is performed using jet substructure techniques, allowing us to build an observable sensible to the energy growth for those operators.
