Scalar coupling limits and diphoton Higgs decay from LHC in an $U(1{)}^{\prime }$ model with scalar dark matter

R. Martinez, J. Nisperuza, F. Ochoa +2

In the context of an nonuniversal $U(1{)}^{\prime }$ extension of the standard model free from anomalies, we introduce a complex scalar singlet candidate to be dark matter. In addition, an ex…
