Title: Muon g - 2 in the aligned two Higgs doublet model

Abstract

In this paper, we study the Two-Higgs-Doublet Model with the aligned Yukawa sector (A2HDM) in light of the observed excess measured in the muon anomalous magnetic moment. We take into account the existing theoretical and experimental constraints with up-to-date values and demonstrate that a phenomenologically interesting region of parameter space exists. With a detailed parameter scan, we show a much larger region of viable parameter space in this model beyond the limiting case Type X 2HDM as obtained before. It features the existence of light scalar states with masses 3 GeV ≲ m_H ≲ 50 GeV, or 10 GeV ≲ m_A ≲ 130 GeV, with enhanced couplings to tau leptons. The charged Higgs boson is typically heavier, with 200 GeV ≲ m_H⁺ ≲ 630 GeV. The surviving parameter space is forced into the CP-conserving limit by EDM constraints. Some Standard Model observables may be significantly modified, including a possible new decay mode of the SMlike Higgs boson to four taus. Lastly, we comment on future measurements and direct searches for those effects at the LHC as tests of the model.

Flavor constraints on two-Higgs-doublet models with general diagonal Yukawa couplings

Journal Article Mahmoudi, F ; Staal, O - Physical Review. D, Particles Fields

We consider constraints from flavor physics on two-Higgs-doublet models (2HDM) with general, flavor-diagonal, Yukawa couplings. Analyzing the charged Higgs contribution to different observables, we find that b{yields}s{gamma} transitions and {Delta}M{sub B{sub d}} restrict the coupling {lambda}{sub tt} of the top quark (corresponding to cot{beta} in models with a Z{sub 2} symmetry) to |{lambda}{sub tt}|<1 for m{sub H}{sup +} < or approx. 500 GeV. Stringent constraints from B meson decays are obtained also on the other third generation couplings {lambda}{sub bb} and {lambda}{sub {tau}{tau},} but with stronger dependence on m{sub H}{sup +}. For the second generation, we obtain constraints on combinationsmore »« less

Top and Higgs flavor changing neutral couplings in two Higgs doublets model

Journal Article Arhrib, Abdesslam ; Departement de Mathematiques, Faculte des Sciences et Techniques, B.P 416 Tanger - Physical Review. D, Particles Fields

We study various channels of top and Higgs flavor changing neutral couplings in the two Higgs doublet model with natural flavor conservation (2HDM-I and 2HDM-II). We update known results about t{yields}c{gamma},cZ,cg and comment on t{yields}ch{sup 0}. The decays t{yields}ch{sup 0} as well as {l_brace}h{sup 0},H{sup 0}{r_brace}{yields}tc are sensitive both to the bottom Yukawa coupling as well as to the trilinear scalar couplings h{sup 0}H{sup +}H{sup -} and H{sup 0}H{sup +}H{sup -}. After imposing unitarity constraints as well as vacuum stability conditions on scalar sector parameters, in 2HDM-II we found that for large tan{beta} > or approx. 40 and rather lightmore »« less

High scale flavor alignment in two-Higgs doublet models and its phenomenology

Journal Article Gori, Stefania ; Haber, Howard E. ; Santos, Edward - Journal of High Energy Physics (Online)

The most general two-Higgs doublet model (2HDM) includes potentially large sources of flavor changing neutral currents (FCNCs) that must be suppressed in order to achieve a phenomenologically viable model. The flavor alignment ansatz postulates that all Yukawa coupling matrices are diagonal when expressed in the basis of mass-eigenstate fermion fields, in which case tree-level Higgs-mediated FCNCs are eliminated. In this work, we explore models with the flavor alignment condition imposed at a very high energy scale, which results in the generation of Higgs-mediated FCNCs via renormalization group running from the high energy scale to the electroweak scale. Using the currentmore »« less

Dark Two Higgs Doublet Model

Journal Article Lee, Hye Sung ; Sher, Marc - Phys. Rev. D

We perform a detailed study of a specific Two Higgs Doublet Model (2HDM) with a U(1) gauge symmetry, instead of a typical Z{sub 2} discrete symmetry, containing a very light gauge boson Z' (GeV scale or below). The Standard Model (SM) fermions do not carry U(1) charges, but induced couplings to the Z' (called the dark Z) are generated through mixing with the SM neutral gauge bosons. Such a light Z' could explain some astrophysical anomalies as well as the muon g-2 deviation, and has been the subject of great experimental interest. We consider the scenario in which the 125more »« less

Heavy Higgs boson decays in the alignment limit of the 2HDM

Journal Article Grzadkowski, Bohdan ; Haber, Howard E. ; Ogreid, Odd Magne ; ... - Journal of High Energy Physics (Online)

The Standard Model (SM)-like couplings of the observed Higgs boson impose strong constraints on the structure of any extended Higgs sector. We consider the theoretical properties and the phenomenological implications of a generic two Higgs doublet model (2HDM). This model constitutes a simple and attractive extension of the SM that is consistent with the observation of the SM-like Higgs boson and precision electroweak observables, while providing a potential new source of CP-violation. In this paper we focus on the so-called Higgs alignment limit of the generic 2HDM, where the neutral scalar field H₁, with the tree-level couplings of the SMmore »« less
