Heavy WIMP through Higgs portal at the LHC

Understand

LHC constraints on Higgs-portal WIMPs are studied.

• Scalar, vector and anti-symmetric tensor fields are considered.
• They are assumed to be heavier than a half of the Higgs boson mass.
• We investigate 8 TeV LHC results on signatures of the vector boson fusion, mono-jet and associated production of the $Z$ boson, which proceed via virtual exchange of the Higgs boson.
