Lepton Portal Dark Matter

Understand

We study a class of simplified dark matter models in which dark matter couples directly with a mediator and a charged lepton.

• This class of Lepton Portal dark matter models has very rich phenomenology: it has loop generated dark matter electromagnetic moments that generate a direct detection signal; it contributes to indirect detection in the cosmic positron flux via dark matter annihilation; it provides a signature of the same-flavor, opposite-sign dilepton plus missing transverse energy at colliders.
• We determine the current experimental constraints on the model parameter space for Dirac fermion, Majorana fermion and complex scalar dark matter cases of the Lepton Portal framework.
• We also perform a collider study for the 14 TeV LHC reach with 100 inverse femtobarns for dark matter parameter space.
