Title: Higgs phenomenology in the minimal $S U (3)_{L} x U (1)_{X}$ model

Abstract

Here, we investigate the phenomenology of a model based on the SU(3)_c×SU(3)_L×U(1)_X gauge theory, the so-called 331 model. Particularly, we focus on the Higgs sector of the model which is composed of three SU(3)_L triplet Higgs fields, and this corresponds to the minimal form to realize phenomenologically acceptable scenario. After the spontaneous symmetry breaking SU(3)_L×U(1)_X→SU(2)_L×U(1)_Y, our Higgs sector effectively becomes that with two SU(2)L doublet scalar fields, in which the first and the second generation quarks couple to the different Higgs doublet from that couples to the third generation quarks. Furthermore, this structure causes the flavour changing neutral current mediated by Higgs bosons at the tree level. By taking an alignment limit of the mass matrix for the CP-even Higgs bosons, which is naturally realized in the case with the breaking scale of SU(3)_L×U(1)_X to be much larger than that of SU(2)_L×U(1)_L, we can avoid current constraints from flavour experiments such as the B⁰-$$\bar{B}$$⁰ mixing even for the Higgs bosons masses being O(100) GeV. In this allowed parameter space, we clarify that a characteristic deviation in quark Yukawa couplings of the standard model-like Higgs boson is predicted, which has a different pattern from that seen in two Higgs doublet models with a softly-broken Z₂ symmetry. We also find that the flavour violating decay modes of the extra Higgs boson, e.g., H/A→tc and H^±→ts can be dominant, and they yield the important signature to distinguish our model from the two Higgs doublet models.

Light sterile neutrino and low scale left-right symmetry in a D-brane inspired $S U (4)_{C} \times S U (2)_{L} \times S U (2)_{R}$ model

Journal Article Leontaris, George K. ; Shafi, Qaisar - Physical Review D

Motivated by the ongoing searches for new physics at the LHC, we explore the low energy consequences of a D-brane inspired SU(4)_C × SU(2)_L × SU(2)_R (4-2-2) model. The Higgs sector consists of an SU(4) adjoint, a pair H + H¯ in (4,1,2) + (4¯,1,2), and a bidoublet field in h(1,2,2). With the SU(4) adjoint, the symmetry breaks to a left-right symmetric SU(3)_C × U(1)_B–L × SU(2)_L× SU(2)_R model. A missing partner mechanism protects the SU(2)_R Higgs doublets in H, H¯, which subsequently break this latter symmetry at around to 10⁴ – 10⁶ GeV to the Standard Model. Anmore »« less

$Z^{}$ -portal right-handed neutrino dark matter in the minimal ${U (1)}_{X}$ extended Standard Model

Journal Article Okada, Nobuchika ; Okada, Satomi - Physical Review D

We consider a concise dark matter (DM) scenario in the context of a non-exotic U(1) extension of the Standard Model (SM), where a new U(1)_X gauge symmetry is introduced along with three generation of right-handed neutrinos (RHNs) and an SM gauge singlet Higgs field. The model is a generalization of the minimal gauged U(1)_B-L (baryon number minus lepton number) extension of the SM, in which the extra U(1)_X gauge symmetry is expressed as a linear combination of the SM U(1)_Y and U(1)_B-L gauge symmetries. We introduce a Z₂-parity and assign an odd-parity only for one RHN among all particles, somore »« less

Nonminimal quartic inflation in classically conformal ${U (1)}_{X}$ extended standard model

Journal Article Oda, Satsuki ; Okada, Nobuchika ; Raut, Digesh ; ... - Physical Review D

We propose quartic inflation with nonminimal gravitational coupling in the context of the classically conformal U (1)_X extension of the standard model (SM). In this model, the U(1)_Xgauge symmetry is radiatively broken through the Coleman-Weinberg mechanism, by which the U(1)_X gauge boson (Z ' boson) and the right-handed Majorana neutrinos acquire their masses. We consider their masses in the range of O (10 GeV ) - O (10 TeV) , which are accessible to high-energy collider experiments. The radiative U (1)_X gauge symmetry breaking also generates a negative mass squared for the SM Higgs doublet, and the electroweak symmetrymore »« less

Inflection-point inflation in a hyper-charge oriented ${U (1)}_{X}$ model

Journal Article Okada, Nobuchika ; Okada, Satomi ; Raut, Digesh - Physical Review D

Inflection-point inflation is an interesting possibility to realize a successful slow-roll inflation when inflation is driven by a single scalar field with its value during inflation below the Planck mass (ΦI≲M_Pl). In order for a renormalization group (RG) improved effective λΦ⁴ potential to develop an inflection-point, the running quartic coupling λ(Φ) must exhibit a minimum with an almost vanishing value in its RG evolution, namely λ(Φ_I)≃0 and β_λ(ΦI)≃0, where β_λ is the beta-function of the quartic coupling. Here in this paper, we consider the inflection-point inflation in the context of the minimal gauged U(1)_X extended Standard Model (SM), which ismore »« less

Classically conformal ${U (1)}^{'}$ extended standard model, electroweak vacuum stability, and LHC Run-2 bounds

Journal Article Das, Arindam ; Oda, Satsuki ; Okada, Nobuchika ; ... - Physical Review D

Here, we consider the minimal U(1)' extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U(1)' gauge symmetry is introduced along with three generations of right-handed neutrinos and a U(1)' Higgs field. Since the classically conformal symmetry forbids all dimensional parameters in the model, the U(1)' gauge symmetry is broken by the Coleman-Weinberg mechanism, generating the mass terms of the U(1)' gauge boson (Z' boson) and the right-handed neutrinos. Through a mixing quartic coupling between the U(1)' Higgs field and the SM Higgs doublet field, the radiative U(1)' gauge symmetry breaking also triggers the breakingmore »« less
