Description

In this talk, we consider a conformal complex singlet extension of the Standard Model with a Higgs portal interaction. Two different scenarios depending on whether the global U(1) symmetry is broken or not have been studied. In the broken phase, including the additional vector-like fermion, we are able to address the recent 750 GeV LHC diphoton excesses. In the unbroken phase, the decay of the complex singlet is protected by the global U(1) symmetry which leads to an ideal cold dark matter candidate. In addition, gauging the global U(1)symmetry, we can construct an asymptotically safe U(1)' leptophobic model. We combine the notion of asymptotic safety with conformal symmetry and use the renormalization group equations as a bridge to connect UV boundary conditions and EW/TeV scale physics. We also provide a detailed example to show one of the boundary conditions may address the LHC diboson anomaly.
