Abstract We present an SO(10) model in which a dimension five operator induces kinetic mixing at the GUT scale between the abelian subgroups U(1) B−L and U(1) R . We discuss in this framework gauge coupling unification and proton decay, as well as

Abstract We discuss the appearance of topological structures from the spontaneous breaking of E 6 to the Standard Model via its maximal subgroup SO(10) × U(1) ψ . They include dumbbells, metastable strings, as well as domain walls bounded by neckla

We discuss E6 based extensions of the Standard Model (SM) containing two varieties of superheavy metastable cosmic strings (CSs) that respectively have neutral and electrically charged current carriers. We employ an extended version of the velocity-d

Abstract We explore a variety of composite topological structures that arise from the spontaneous breaking of SO(10) to SU(3) c × U(1) em via one of its maximal subgroups SU(5) × U(1) χ , SU(4) c × SU(2) L × SU(2) R , and SU(5) × U(1) X (also k

Abstract We explore some experimentally testable predictions of an SO(10) axion model which includes two 10-plets of fermions in order to resolve the axion domain wall problem. The axion symmetry can be safely broken after inflation, so that the isoc

We explore the gravitational wave spectrum generated by string-wall structures in an SO(10) (Spin(10)) based scenario of pseudo-Goldstone boson dark matter (pGDM) particle. This dark matter candidate is a linear combination of the Standard Model (SM)

Abstract We consider a $$U(1)_{B-L}$$ U ( 1 ) B - L model with a $$Z^\prime $$ Z ′ portal Dirac fermion dark matter (DM) $$\chi $$ χ of low mass which couples very weakly to the $$B - L$$ B - L gauge boson $$Z^\prime $$ Z ′ . An arbitrary $$B-L$

Abstract We study the low energy implications of a trinification model based on the gauge symmetry $$G= SU(3)_c \times SU(3)_L \times SU(3)_R$$ G = S U ( 3 ) c × S U ( 3 ) L × S U ( 3 ) R , without imposing gauge coupling unification. A minimal mod

Abstract We explore the implications of resolving the muon $$g-2$$ g - 2 anomaly in a $$SU(4)_c \times SU(2)_L \times SU(2)_R$$ S U ( 4 ) c × S U ( 2 ) L × S U ( 2 ) R model, where the soft supersymmetry breaking scalar and gaugino masses break the

We perform an analysis of the predictions of several supersymmetric Grand Unified Theories (GUTs) for Dark Matter and the measurements of the muon anomalous magnetic moment (muon g − 2) consistent with possible Lepton Flavor Violating (LFV) signal
