“…where α X = g 2 X /(4π). As shown in earlier works [44][45][46][47][48], the only allowed region where such neutral gauge boson contribution can explain muon AMM is in the sub-GeV regime with corresponding gauge coupling smaller than 10 −3 . Since we consider heavy gauge boson limit, the contribution from such neutral gauge bosons remain suppressed.…”

We study an Abelian gauge extension of the standard model with fermion families having nonuniversal gauge charges. The gauge charges and scalar content are chosen in such an anomaly-free way that only the third generation fermions receive Dirac masses via renormalisable couplings with the Higgs boson. Incorporating additional vector like fermions and scalars with appropriate U (1) charges can lead to radiative Dirac masses of first two generations with neutral fermions going in the loop being dark matter candidates. Focusing on radiative muon mass, we constrain the model from the requirement of satisfying muon mass, recently measured muon anomalous magnetic moment by the E989 experiment at Fermilab along with other experimental bounds including the large hadron collider (LHC) limits. The anomalous Higgs coupling to muon is constrained from the LHC measurements of Higgs to dimuon decay. The singlet fermion dark matter phenomenology is discussed showing the importance of both annihilation and coannihilation effects. Incorporating all bounds lead to a constrained parameter space which can be probed at different experiments.

“…In addition, the extra U(1) charges for the three generations of left-handed fermions are 0 and ±2. This charge assignment is reminiscent of the charges in the U(1) Lµ−Lτ model [52][53][54][55] that has been extensively studied, for instance, in the contexts of the neutrino physics [56][57][58][59], cosmology [60][61][62][63][64][65][66][67][68][69][70][71][72][73], and realization of the U(1) Lµ−Lτ symmetry from high-energy theory [74]. Although this model itself predicts five generations of fermions, by manipulating the two generations that appear in excess, we may be able to obtain left-handed fermions with U(1) Lµ−Lτ charge for three generations, which could potentially explain the generation structure of the fermions in the SM.…”

We investigate the twelve-dimensional gauge-Higgs unification models with an eight- dimensional coset space as the extra space. For each model, we apply the coset space dimensional reduction procedure and examine the particle contents of the resulting four-dimensional theory. All combinations of inputs to the procedure are exhaustively analyzed under several assumptions. As a result, some twelve-dimensional SO(18) gauge theories lead to models of the SO(10) × U(1) grand unified theory in four dimensions, where fermions of the Standard Model appear in multiple generations along with scalars that may break the electroweak symmetry. The representations of the obtained scalars and fermions are summarized.

We propose a new class of U(1)μ−τ gauged model that can explain recent flavor anomalies such as muon g − 2, b → sμ+μ−, as well as include a scalar dark matter candidate while satisfying all the phenomenological constraints. For this purpose, we add new vectorlike quarks and leptons as well as two inert singlet scalars, one leptophilic and the other leptophobic. In our model b → sμ+μ− anomalies can be explained by loop induced interactions among the SM, exotic quarks, and Z′ gauge boson. In our numerical analysis, we show allowed region of our model to be narrow, and it would be tested soon, for example by searching for 4 muons and dimuon + missing transverse momentum from pp → μ+μ−Z′ and $$ pp\to {\nu}_{\mu, \tau }{\overline{\nu}}_{\mu, \tau }Z^{\prime } $$ pp → ν μ , τ ν ¯ μ , τ Z ′ followed by $$ Z^{\prime}\to {\mu}^{+}{\mu}^{-},{\nu}_{\mu, \tau }{\overline{\nu}}_{\mu, \tau } $$ Z ′ → μ + μ − , ν μ , τ ν ¯ μ , τ at the LHC.
