Electroweak: Dark Sector
- James Dent (Sam Houston State University)
Dark matter is known to make up more than 75% of matters of the universe. However, its nature remains to be unveiled. Over the several decades, extensive studies have been done on the weak scale mass regime, but there have been no positive results thus far. This naturally led to an interest in the dark matter models in areas other than the weak scale.

Recent discoveries of a new scalar boson, the gravitational wave and the black hole greatly advance our understanding of the nature of the universe. The 95% of the universe, however, is yet to be uncovered. Of these is the dark matter thought to make up about a quarter of the universe. Dark matter has been searched both directly and indirectly. Direct searches have hard bounds in the low...
We explore the effective field theory of a vector field X_mu that has a Stückelberg mass. The absence of a gauge symmetry for X implies Lorentz-invariant operators are constructed directly from X_mu. Beyond the kinetic and mass terms, allowed interactions at the renormalizable level include X^4, H^2 X^2 and X^mu j_mu, where j_mu is a global current of the SM or of a hidden sector. We show that...
