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

Abstract

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 →WW and their correlations from the region of the parameter space that satisfies all available constraints including precision electroweak observables and from pair production of vectorlike leptons. Large contributions, close to current limits, favor small tan β region of the parameter space. We find that, as a result of adopted cuts in experimental analyses, the contribution to pp → W W can be an order of magnitude larger than the contribution to H → W W . Thus, future precise measurements of pp → W W will further constrain the parameters of the model. Also, we also consider possible contributions tomore »« less

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

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

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 kinematicmore »« less

Muon $g - 2$ in two-Higgs-doublet models with vectorlike leptons

Journal Article Dermisek, Radovan ; Hermanek, Keith ; McGinnis, Navin - Physical Review D

We calculate contributions to the anomalous magnetic moment of the muon from heavy neutral and charged Higgs bosons and new leptons in two Higgs doublet models extended by vectorlike leptons. We present detailed predictions of two models with type-II couplings to standard model fermions, motivated by a Z₂ symmetry and supersymmetry. In addition, we compare the results with the standard model extended by vectorlike leptons. We find that the model motivated by a Z₂ symmetry can generate much larger contributions to the magnetic moment compared to the standard model, even by two orders of magnitude due to tan² β enhancement,more »« less

Hunting for vectorlike quarks

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

We analyze decays of vectorlike quarks in extensions of the standard model and a two Higgs doublet model. We identify several typical patterns of branching ratios of the lightest new up-type quark, t₄, and down-type quark, b₄, depending on the structure of Yukawa couplings that mix the vectorlike and standard model quarks (we assume only mixing with the third generation) and also on their doublet or singlet nature. We find that decays into heavy neutral or charged Higgs bosons, when kinematically open, can easily dominate and even be close to 100%: b₄ → Hb at medium to large tan β,more »« less

Cascade decays of heavy Higgs bosons through vectorlike quarks in two Higgs doublet models

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

We study cascade decays of heavy neutral Higgs bosons through vectorlike quarks. We focus on scenarios where decay modes into pairs of vectorlike quarks are not kinematically open which extends the sensitivity of the LHC to larger masses. Assuming only mixing with the third family of standard model quarks the new decay modes of heavy Higgs bosons are: H → t4t → Wbt, Ztt, htt and H → b4b → Wtb, Zbb, hbb, where t4 (b4) is the new up-type (down-type) quark mass eigenstate.
