Dark Higgs Models at the 7 TeV LHC

Understand

We study how collider data and electroweak precision observables affect the parameter space of models including a new dark force mediated by a massive U(1) gauge boson.

• It acquires mass via a Higgs mechanism in the dark sector which is connected to the Standard Model through kinetic mixing of the two U(1) gauge bosons and the Higgs potential.
• We assess the impact of the 7 TeV LHC and show that most of the parameter space of the model can be probed with an integrated luminosity of 15 fb^-1.
