Constraints from "Higgs mass and Cross-Section Measurements at a 500GeV CLIC Machine, Operating at sqrt(s)= 350GeV and 500GeV" |

Following the selection of the lepton pair: the Transverse momentum and polar angle of the lepton pair were calculated. Also Acollinearity and Acopolanarity of the leptons were calculated. |

> | Cuts from ZFinder
The ZFinder works by using the fact that the electric calorimeter does not detect any muons.
Vector _pfovec is the detected particle vector.
If the energy of _pfovec is less than the momentum cut for fermion from Z decay then it is not a muon.
If the electric calorimetry is greater than the cut on the muon ECAL energy then not a muon.
If the hadronic calorimetry is greater than the cut on the muon HCAL energy then not a muon.
If the energy of _pfovec is less than the momentum cut for fermion from Z decay then it is not an electron.
If the electric calorimeter is less than the cut on the electron ECAL energy, then not an electron.
If the hadronic calorimeter is greater than the cut on the electron HCAL energy, then not an electron.
- Momentum cut for fermion from Z decay, ' _momentumCut ' = 10
- Cut on muon ECAL energy, ' _muonEcalEnergyCut '= 2.5
- Cut on muon HCAL energy, ' _muonHcalEnergyCut '= 10
- Cut on electron ECAL energy, ' _electronEcalEnergyCut ' = 10
- Cut on electron HCAL energy, ' _electronHcalEnergyCut ' = 10
NB: ZFinder tautau decay mode and qq decay mode not implemented.

In mumuX channel, the mass of the selected lepton pair, Transverse momentum of lepton pair, and the recoil mass were investigated. The made distributions made from the properties motivated the cuts: |
