Title: 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

Abstract

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. An inverse seesaw mechanism generates masses for the observed neutrinos and also yields a keV sterile neutrino that can play the role of dark matter if its mass lies in the keV range. Other phenomenological implications, including proton decay, are briefly discussed.

Millicharged scalar fields, massive photons and the breaking of ${S U (3)}_{C} \times {U (1)}_{EM}$

Journal Article West, Jennifer Rittenhouse - Physical Review D

Under the assumption that the current epoch of the Universe is not special, i.e., is not the final state of a long history of processes in particle physics, the cosmological fate of SU(3)_C × U(1)_EM is investigated. Spontaneous symmetry breaking of U(1)_EM at the temperature of the Universe today is carried out. The charged scalar field Φ_EM which breaks the symmetry is found to be ruled out for the charge of the electron, q = e. Scalar fields with millicharges are viable and limits on their masses and charges are found to be q ≲ 10 –3 e and m_ΦEMmore »« less

Supersymmetric $S U (5) \times U (1)_{χ}$ and the weak gravity conjecture

Journal Article Pal, Abhishek ; Shafi, Qaisar - Physical Review. D.

The gauge symmetry SU( ) × U(1)χ is the unique maximal subgroup of SO(10) which retains manifest unification at M_GUT of the Standard Model gauge couplings, especially if low scale supersymmetry is present. The spontaneous breaking of U(1)χ at some intermediate scale leaves unbroken a Z₂ symmetry which is precisely “matter” parity. This yields a stable supersymmetric dark matter particle as well as topologically stable cosmic strings.

Leptonic $C P$ violation and leptogenesis in minimal supersymmetric $SU (4)_{c} \times SU (2)_{L} \times SU (2)_{R}$

Journal Article Okada, Nobuchika ; Shafi, Qaisar - Physical Review. D.

We consider a supersymmetric SU(4)_c × SU(2)_L × SU(2)_R model with a minimal number of Higgs multiplets and Dirac and Majorana CP-violating phases in the neutrino flavor mixing matrix. The model incorporates the charged fermion masses and quark mixings, and uses type I seesaw to explain the solar and atmospheric neutrino oscillations. With the neutrino oscillation data of two mass squared differences and three flavor mixing angles, we employ thermal leptogenesis and the observed baryon asymmetry to find the allowed regions for the Dirac and Majorana phases. For a normal neutrino mass hierarchy, we find that the observed baryon asymmetrymore »« 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

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

Journal Article Okada, Hiroshi ; Okada, Nobuchika ; Orikasa, Yuta ; ... - Physical Review D

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-more »« less
