Gluino pair production Analysis



Final State:

  • 4 jets at central region
  • 2 scattered protons at CT-PPS
  • MET due to the neutralino
Mass hierarchy: m(squark) >> m(gluino)
  • main production: gluino pairs
  • dominat decay: gluino -> q qbar neutralino
  • typical signature: >=4 jets + MET + X

Chargino pair production via photon fusion



Final state:

  • 2 leptons (e-e or e-muon or muon-muon) with opposite charges at central region
  • 2 scattered protons detected at CT-PPS
  • MET due to the neutrinos and neutralinos
  • acoplanarity
