The kinematic distributions of the lepton pairs produced in the decay of the Standard Model Higgs to ZZ and WW are related to the polarization fractions of the virtual vector bosons. The full amplitude can be decomposed analytically into a sum of polarized terms. Several observables, in particular the invariant mass of two charged leptons, one from each of the bosons, and the lepton angular distribution in the vector boson center of mass are shown to be sensitive to the boson polarizations.

  1. $CP$ violation in the $HZZ$ vertex and left-right asymmetries

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Flavor-changing Z and Higgs couplings can induce CP-violating HZZ form factors up to about 10^-7, and a new asymmetry in Z* -> Z H is proposed to search for them.
