Lepton-mass effects in the decaysH→ZZ*→ℓ+ℓ−

Abstract

We consider τ -lepton mass effects in the cascade decays H → Z(→ ℓ + ℓ − ) + Z * (→ τ + τ − ) and H → W − (→ ℓ −ν ℓ ) + W + * (→ τ + ν τ ). Since the scale of the problem is set by the off-shellness q 2 of the respective gauge bosons in the limits ( for the angular decay distributions of the final-state leptons. We also briefly consider the corresponding off-shell -off-shell decays H

“…In this Appendix we provide a synopsis of how to obtain the angular decay distributions for the decays B → D ( * ) ℓ −ν ℓ following the description in [40,64]. The covariant representation of the angular decay distribution is given by…”

NLO EW and QCD corrections to polarized ZZ production in the four-charged-lepton channel at the LHC

“…Thanks to the possibility of reconstructing all particles in the final state, the production of four charged leptons provides a large number of angular observables that are sensitive to the spin structure of the underlying resonances, both in the case of the Higgs and single-Z decay into four leptons, and in the case of the leptonic decay of two Z bosons. In fact, the Higgs decay into four leptons has been widely studied [38][39][40][41][42][43][44][45][46][47] and then measured with Run-2 data [1][2][3][4][48][49][50][51] with the purpose of determining the spin and parity of the Higgs boson as well as its CP properties via angular and energy correlations.…”

Gauge Dependence of the Gauge Boson Projector

“…with ε( k, 1) = (0; 1, 0, 0), ε( k, 2) = (0; 0, 1, 0) and ε( k, 3) = (0; 0, 0, 1). If the gauge boson is offshell, it is described by the unitary projector (ξ V → ∞), containing also a scalar component [8],…”
