1.Generator: MCFM 2. PDF: MSTW2008nlo90cl 3.Generation level cut: 1)muon channel: pT_μ>15GeV, |eta_μ|<2.47 2)neotrino channel: MET>90GeV 3)Λ=10000TeV 4)pT_ϒ>100GeV, |eta_ϒ|<2.37 with crack removed 5)0 jet exclusive MC sample generation 2

4 Likelihood 1.Only calculate the expected likelihood (set N observed as N expected ) 2.Consider some uncertainties such as efficiency, theoretical which use last year result. 3.For 1D using 2000 points for each ATGC parameter; For 2D using 200*200 points for each 2 ATGC parameters. Muon channel 2D likelihood distribution Muon channel 1D likelihood distribution
5
5 ATGC parameter limits set 1.For 1D exactly as last year method 2.For 2D cut a plate in 2D likelihood and get the boundaries as 2D parameter limits Muon channel 2D likelihood distribution 95% plate
