Title: Contributions of flavor violating couplings of a Higgs boson to pp → W W

Abstract

We study contributions to pp→W⁺W^-→ℓν_ℓℓ'ν_ℓ' in models with a new Higgs boson, H, and a neutral lepton, ν₄, with couplings H - ν₄ - ν_μ and W- ν₄ - μ through the process pp → H → ν₄ν_μ → Wμν_μ → ℓν _ℓ μν _μ. Contrary to naive expectations, we find that contributions to pp → W W can be very large while satisfying constraints from standard H → W W and H → γγ searches. Even the excess observed by ATLAS in pp → W W , if taken at face value, can be easily accommodated. The various kinematic distributions fit nicely the experimentally determined ones. Lastly, this scenario can arise for example in a two Higgs doublet model with vectorlike leptons.

Two Higgs doublet model with vectorlike leptons and contributions to pp → W W and H → W W

Journal Article Dermíšek, Radovan; Lunghi, Enrico; Shin, Seodong - Journal of High Energy Physics (Online)

In this paper, we study a two Higgs doublet model extended by vectorlike leptons mixing with one family of standard model leptons. Generated flavor violating couplings between heavy and light leptons can dramatically alter the decay patterns of heavier Higgs bosons. We focus on pp → H → ν₄ν_μ → W μν_μ, where ν₄ is a new neutral lepton, and study possible effects of this process on the measurements of pp → W W and H → W W since it leads to the same final states. We discuss predictions for contributions to pp → W W and H →WWmore »« less

Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb^-1 of $$ \sqrt{s}=13 $$ TeV pp collisions with the ATLAS detector

Journal Article Aaboud, M.; Aad, G.; Abbott, B.; ... - Journal of High Energy Physics (Online)

Here, a search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the $$v\bar{v}$$$$b\bar{b}$$, ℓ^±ν$$b\bar{b}$$, and ℓ⁺ℓ^-$$b\bar{b}$$ final states, where ℓ^± = e^± or μ^±, in pp collisions at $$\sqrt{s}$$ =13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb^-1 collected with the ATLAS detector at the Large Hadron Collider during the 2015 and 2016 data-taking periods. The search is conducted by examining the reconstructed invariant or transverse mass distributions of W h and Zh candidates for evidence of a localised excess in the mass rangemore »« less

New constraints and discovery potential for Higgs to Higgs cascade decays through vectorlike leptons

Journal Article Dermíšek, Radovan; Lunghi, Enrico; Shin, Seodong - Journal of High Energy Physics (Online)

One of the cleanest signatures of a heavy Higgs boson in models with vectorlike leptons is H→e^±₄ℓ^∓→hℓ⁺ℓ^- which, in two Higgs doublet model type-II, can even be the dominant decay mode of heavy Higgses. Among the decay modes of the standard model like Higgs boson, h, we consider bb¯¯ and γγ as representative channels with sizable and negligible background, respectively. We obtained new model independent limits on production cross section for this process from recasting existing experimental searches and interpret them within the two Higgs doublet model. In addition, we show that these limits can be improved by about twomore »« less

Searches for lepton-flavour-violating decays of the Higgs boson into $eτ$ and $μτ$ in $$ \sqrt{s}$$ = 13 TeV pp collisions with the ATLAS detector

Journal Article Aad, G.; Abbott, B.; Abbott, D.; ... - Journal of High Energy Physics (Online)

This paper presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ, performed using data collected with the ATLAS detector at the LHC. The searches are based on a data sample of proton-proton collisions at a centre-of-mass energy $$\sqrt{s}$$ = 13 TeV, corresponding to an integrated luminosity of 138 fb^–1. Leptonic (τ → ℓν_ℓν_τ) and hadronic (τ → hadrons ν_τ) decays of the τ-lepton are considered. Two background estimation techniques are employed: the MC-template method, based on data-corrected simulation samples, and the Symmetry method, based on exploiting the symmetry between electrons andmore »« less

Measurements of Higgs boson production cross-sections in the $H → τ^+τ^-$ decay channel in pp collisions at $$\sqrt{s}$$ = 13 TeV with the ATLAS detector

Journal Article Aad, G.; Abbott, B.; Abbott, D.; ... - Journal of High Energy Physics (Online)

Measurements of the production cross-sections of the Standard Model (SM) Higgs boson (H) decaying into a pair of τ-leptons are presented. The measurements use data collected with the ATLAS detector from pp collisions produced at the Large Hadron Collider at a centre-of-mass energy of $$\sqrt{s}$$ = 13 TeV, corresponding to an integrated luminosity of 139 fb^-1. Leptonic (τ → ℓν_ℓν_τ) and hadronic (τ → hadrons ν_τ) decays of the τ-lepton are considered. All measurements account for the branching ratio of H → ττ and are performed with a requirement |y_H| < 2.5, where y_H is the true Higgs boson rapidity.more »« less
