Fitting result Fit cross-section as function of h3 and h4: Less statistics
Likelihood Only calculate the expected likelihood (set Nobserved as Nexpected) Consider some uncertainties such as efficiency, theoretical which use last year result. For 1D using 2000 points for each ATGC parameter; For 2D using 200*200 points for each 2 ATGC parameters. Muonchannel 1D likelihood distribution Muonchannel 2D likelihood distribution
ATGC parameter limits set For 1D exactly as last year method For 2D cut a plate in 2D likelihood and get the boundaries as 2D parameter limits 95% plate Muonchannel 2D likelihood distribution
