Ongoing Physics Analyses

Higgs boson

We study the recently discovered Higgs boson using three experimental signatures.

  • HZZ → 4 leptons, focusing on the Higgs boson mass.
  • HWW → lνlν, focusing on the production cross-section and vector-boson-fusion production mechanism.
  • ZHllbb, a yet-to-be-discovered process.


We search for electroweak production of charginos and neutralinos.

  • χ1+χ1W+W + 2 LSPs → 2 leptons + missing ET.
  • χ1±χ20W±H + 2 LSPs → 1 lepton + 2 b jets + missing ET.
