“…Among various models that include extended Higgs sectors, this paper discusses a model with additional U(1) D × U(1) B−L gauge symmetry proposed in [37]. This model attempts to simultaneously explain neutrino mass, dark matter, and the baryon asymmetry of the Universe by the TeV-scale physics without fine-tuning.…”

“…After the scalars gain their VEV, the gauge boson and scalar Higgs will have mass. There is a notable lack of previous work [37] where the mass of gauge bosons has not been explored. Thus to complement the proposed model, we will investigate the mass of the gauge boson and re-investigate the scalars Higgs sector in detail through this work.…”

We have investigated the boson sector in an extended standard model (SM) with additional U(1)D symmetry. In the proposed model, the singlet scalar and doublet scalar Higgs are added in addition to the SM-like scalar Higgs. These scalars are also coupled to the gauge boson fields. In this work, we calculate the masses of both gauge and scalar Higgs bosons. Their masses are obtained through spontaneous symmetry breaking using the Higgs fields with non-zero vacuum expectation values. We also study numerically the positivity conditions of the vacuum expectation value of the scalars. In particular, we perform scanning of the parameter space of the potential and study the obtained scalar mass dependence on the parameter of the model.

We propose a framework to address the observed baryon asymmetry considering neutrinos as Dirac particles and dark matter to be self-interacting. The Standard Model is extended by U(1)B−L × U(1)D symmetry. In addition to the three right-handed neutrinos, the Standard Model particle content is extended by two more fermion fields; one of them is a S U(2) singlet and the other one is S U(2) doublet, both charged under the extended symmetry. A Z2 symmetry is imposed under which the doublet is positive while the singlet is negative. The singlet, being the lightest dark sector particle, acts as the dark matter. The U(1)D symmetry of the dark sector is spontaneously broken and the corresponding gauge boson Z′ not only mediates the self-interaction among dark matter particles, but also facilitates the annihilation of the symmetric component of dark matter. CP-violating out of equilibrium decay of another heavy Z2 odd S U(2) scalar doublet N into leptonic and dark sectors produce the observed baryon asymmetry and dark matter density. Moreover, Z′ also mixes with the standard model Z-boson opening up a portal for the direct detection of dark matter.
