Title: On-shell interference effects in Higgs boson final states

Abstract

Top quark loops in Higgs production via gluon fusion at large invariant final state masses can induce important interference effects in searches for additional Higgs bosons as predicted in, e.g., Higgs portal scenarios and the minimal supersymmetric Standard Model when the heavy scalar is broad or the final state resolution is poor. Currently, the limit setting as performed by both ATLAS and CMS is based on injecting a heavy Higgs-like signal neglecting interference effects. In this study, we perform a study of such “on-shell” interference effects in pp → ZZ and find that they lead to a ≲O(30%) width scheme-dependent modification of the signal strength. Finally, including the continuum contributions to obtain, e.g., the full pp → ZZ → 4l final state, this modification is reduced to the 10% level in the considered intermediate mass range.

Constraints on new phenomena via Higgs boson couplings and invisible decays with the ATLAS detector

Journal Article Aad, G. - Journal of High Energy Physics (Online)

The ATLAS experiment at the LHC has measured the Higgs boson couplings and mass, and searched for invisible Higgs boson decays, using multiple production and decay channels with up to 4.7 fb^-1 of pp collision data at √s=7 TeV and 20.3 fb^-1 at √s=8 TeV. In the current study, the measured production and decay rates of the observed Higgs boson in the γγ, ZZ, W W , Zγ, bb, τ τ , and μμ decay channels, along with results from the associated production of a Higgs boson with a top-quark pair, are used to probe the scaling of the couplingsmore »« less

Interference effect on a heavy Higgs resonance signal in the $γ γ$ and $Z Z$ channels

Journal Article Song, Jeonghyeon ; Yoon, Yeo Woong ; Jung, Sunghoon - Physical Review D

The resonance-continuum interference is usually neglected when the width of a resonance is small compared to the resonance mass. We reexamine this standard by studying the interference effects in high-resolution decay channels, γγ and ZZ, of the heavy Higgs boson H in nearly aligned two-Higgs-doublet models. For the H with a sub-percent width-to-mass ratio, we find that, in the parameter space where the LHC 14 TeV ZZ resonance search can be sensitive, the interference effects can modify the ZZ signal rate by O(10)% and the exclusion reach by O(10) GeV. In other parameter space where the ZZ or γγ signalmore »« less

Constraints on the off-shell Higgs boson signal strength in the high-mass ZZ and WW final states with the ATLAS detector

Journal Article Aad, G. ; Abbott, B. ; Abdallah, J. ; ... - European Physical Journal. C, Particles and Fields

Measurements of the ZZ and WW final states in the mass range above the $2m_Z$ and $2m_W$ thresholds provide a unique opportunity to measure the off-shell coupling strength of the Higgs boson. This study presents constraints on the off-shell Higgs boson event yields normalised to the Standard Model prediction (signal strength) in the $ZZ \rightarrow 4\ell $, $ZZ\rightarrow 2\ell 2\nu $ and $WW\rightarrow e\nu \mu \nu $ final states. The result is based on pp collision data collected by the ATLAS experiment at the LHC, corresponding to an integrated luminosity of 20.3 fb$^{-1}$ at a collision energy of $\sqrt{s}=8$ TeV.more »« less
