Diboson Interference Resurrection

Understand

High-energy diboson processes at the LHC are potentially powerful indirect probes of heavy new physics, whose effects can be encapsulated in higher-dimensional operators or in modified Standard Model couplings.

• An obstruction however comes from the fact that leading new physics effects often emerge in diboson helicity amplitudes that are anomalously small in the Standard Model.
• As such, the formally leading Standard Model/New Physics interference contribution cancels in inclusive measurements.
• This paper describes a solution to this problem.
