Abstract

Diboson cross section measurements provide important tests of the electroweak (EWK) sector of the Standard Model (SM) by measuring precisely the triple and quartic gauge couplings. Any deviation in the measurement of the strength of these couplings would provide evidence for physics beyond the SM.

Notes

  1. 1.

    Some generators, such as Powheg, have a built-in algorithm to assignment daughter particles to parent bosons; however, this procedure differs across generators. The SHERPA generator does not explicitly assign the leptons to either the W or Z bosons due to the quantum-mechanical ambiguity of events with three leptons and the associate interference effect. A uniform assignment procedure ensures that differences in fiducial cross section predictions are not due to nonphysical assignment of leptons.
