Title: Gauge U(1) dark symmetry and radiative light fermion masses

Abstract

A gauge U (1) family symmetry is proposed, spanning the quarks and leptons as well as particles of the dark sector. The breaking of U (1) to Z(2) divides the two sectors and generates one-loop radiative masses for the first two families of quarks and leptons, as well as all three neutrinos. We study the phenomenological implications of this new connection between family symmetry and dark matter. In particular, a scalar or pseudoscalar particle associated with this U (1) breaking may be identified with the 750 GeV diphoton resonance recently observed at the Large Hadron Collider (LHC).

Gauge $B – L$ model with residual $Z_{3}$ symmetry

Journal Article Ma, Ernest ; Pollard, Nicholas ; Srivastava, Rahul ; ... - Physics Letters B

We study a gauge B–L extension of the standard model of quarks and leptons with unconventional charges for the singlet right-handed neutrinos, and extra singlet scalars, such that a residual Z₃ symmetry remains after the spontaneous breaking of B–L. The phenomenological consequences of this scenario, including the possibility of long-lived self-interacting dark matter and Z' collider signatures is discussed. Lepton number L is a familiar concept. It is usually defined as a global U (1) symmetry, under which the leptons of the standard model (SM), i.e. e,μ,τ together with their neutrinos ν_e,ν_μ,ν_τ have L=1, and all other SM particles havemore »« less

Dark Gauge U(1) symmetry for an alternative left–right model

Journal Article Kownacki, Corey ; Ma, Ernest ; Pollard, Nicholas ; ... - European Physical Journal. C, Particles and Fields

An alternative left–right model of quarks and lep-tons, where the SU(2)_R lepton doublet (ν, l)_R is replaced with (n, l)_R so that n_R is not the Dirac mass partner of ν_L, has been known since 1987. Previous versions assumed a global U(1)_S symmetry to allow n to be identified as a dark-matter fermion. We propose here a gauge extension by the addition of extra fermions to render the model free of gauge anomalies, and just one singlet scalar to break U(1)_S.This results in two layers of dark matter, one hidden behind the other.

Anomalous leptonic U(1) symmetry: Syndetic origin of the QCD axion, weak-scale dark matter, and radiative neutrino mass

Journal Article Ma, Ernest ; Restrepo, Diego ; Zapata, Óscar - Modern Physics Letters A

The well-known leptonic U(1) symmetry of the Standard Model (SM) of quarks and leptons is extended to include a number of new fermions and scalars. Here, the resulting theory has an invisible QCD axion (thereby solving the strong CP problem), a candidate for weak-scale dark matter (DM), as well as radiative neutrino masses. A possible key connection is a color-triplet scalar, which may be produced and detected at the Large Hadron Collider.

New U(1) gauge model of radiative lepton masses with sterile neutrino and dark matter

Journal Article Adhikari, Rathin ; Borah, Debasish ; Ma, Ernest - Physics Letters B

Here, an anomaly-free U(1) gauge extension of the standard model (SM) is presented. Only one Higgs doublet with a nonzero vacuum expectation is required as in the SM. New fermions and scalars as well as all SM particles transform nontrivially under this U(1), resulting in a model of three active neutrinos and one sterile neutrino, all acquiring radiative masses. Charged-lepton masses are also radiative as well as the mixing between active and sterile neutrinos. At the same time, a residual Z₂ symmetry of the U(1) gauge symmetry remains exact, allowing for the existence of dark matter.

A 750 GeV messenger of dark conformal symmetry breaking

Journal Article Davoudiasl, Hooman ; Zhang, Cen - Physical Review D

The tentative hints for a diphoton resonance at a mass of ~750 GeV from the ATLAS and CMS experiments at the LHC may be interpreted as first contact with a “dark” sector with a spontaneously broken conformal symmetry. The implied TeV scale of the dark sector may be motivated by the interaction strength required to accommodate a viable thermal relic dark matter (DM) candidate. We model the conformal dynamics using a Randall-Sundrum-type five-dimensional geometry whose IR boundary is identified with the dynamics of the composite dark sector, while the Standard Model (SM) matter content resides on the UV boundary, correspondingmore »« less
