A bstractWe study a class of non-exotic minimal U(1)′ extensions of the Standard Model, which includes all scenarios that are anomaly-free with the ordinary fermion content augmented by one Right-Handed neutrino per generation, wherein the new Abelian gauge group is spontaneously broken by the non-zero Vacuum Expectation Value of an additional Higgs singlet field, in turn providing mass to a Z′ state. By adopting the B − L example, whose results can be recast into those pertaining to the whole… 
Reappraisal of constraints on Z′ models from unitarity and direct searches at the LHC
In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional U(1) symmetry leading to a new neutral gauge boson (Z′),
Constraining a general U(1)′ inverse seesaw model from vacuum stability, dark matter, and collider
We consider a class of gauged $U(1)$ extensions of the Standard Model (SM), where the light neutrino masses are generated by an inverse seesaw mechanism. In addition to the three right handed
Nonuniversal U(1)X extension to the MSSM with three families
We propose a supersymmetric extension of the anomaly-free and three families nonuniversal $U(1)$ model, with the inclusion of four Higgs doublets and four Higgs singlets. The quark sector is extended
Nonuniversal anomaly-free U(1) model with three Higgs doublets and one singlet scalar field
The flavor problem, neutrino physics and the fermion mass hierarchy are important motivations to extend the Standard Model into the TeV scale. A new family non-universal extension is presented with
Z ′ -portal right-handed neutrino dark matter in the minimal U ( 1 ) X extended Standard Model
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
Right-handed neutrino dark matter in the classically conformal U (1 ) ' extended standard model
We consider the dark matter (DM) scenario in the context of the classically conformal U(1)' extended standard model (SM), with three right-handed neutrinos (RHNs) and the U(1)' Higgs field. The model
Implications of right-handed neutrinos in $B-L$ extended standard model with scalar dark matter
We investigate the Standard Model (SM) with a U(1)B−L gauge extension where a B−L charged scalar is a viable dark matter (DM) candidate. The dominant annihilation process, for the DM particle is
Heavy Majorana neutrino pair productions at the LHC in minimal U(1) extended Standard Model
In our recent paper (Das et al. in Phys Rev D 97:115023, 2018) we explored a prospect of discovering the heavy Majorana right-handed neutrinos (RHNs) at the future LHC in the context of the minimal
Phenomenology of minimal Z' models: from the LHC to the GUT scale
We consider a class of minimal abelian extensions of the Standard Model with an extra neutral gauge boson $Z'$ at the TeV scale. In these scenarios an extended scalar sector and heavy right-handed
Light, long-lived B − L gauge and Higgs bosons at the DUNE near detector
Abstract The low-energy U(1)B−L gauge symmetry is well-motivated as part of beyond Standard Model physics related to neutrino mass generation. We show that a light B − L gauge boson Z′ and the
