Constraining Minimal $U(1{)}_{B-L}$ model from Dark Matter Observations

Abstract

We study the $B-L$ gauge extension of the Standard Model which contains a singlet scalar and three right-handed neutrinos. The vacuum expectation value of the singlet scalar breaks the $U(1{)}_{B-L}$ symmetry. Here the third generation right-handed neutrino is qualified as the dark matter candidate, as an artifact of $Z_2$-charge assignment. Relic abundance of the dark matter is consistent with WMAP9 and PLANCK data, only near scalar resonances where dark matter mass is almost half of the scalar boson masses. Requiring correct relic abundance, we restrict the parameter space of the scalar mixing angle and mass of the heavy scalar boson of this model. Besides this, the maximum value of spin-independent scattering cross-section off nucleon is well-below the {\sc Xenon100} and recent LUX exclusion limits and can be probed by future {\sc Xenon1T} experiment. In addition, we compute the annihilation of the dark matter into two photon final state in detail and compare with the Fermi-LAT upper bound on $⟨\sigma v{⟩}_{\gamma \gamma }$ for NFW and Einasto profile.
