Step 7: fitMtt

Presentation

The aim of this utility is to fit tt mass spectrum, especially to fit the background with the right PDF (background + signal) and to extract the number of signal events. It carries also the likelihood scan.

     background + signal

   --workspace <string>
     Use a custom workspace containing the signal pdf to use

   --config-file <string>
     Configuration file name containing fit parameters

   --batch
     Run in batch mode

   -v,  --verbose
     Verbose mode

   --b-tag <int>
     Number of b-tagged jets

   --muons-only
     Compute limits using only semi-mu data

   --bkg-only
     Fit using background model only

   --eff-file <string>
     File where efficiences are stored (JSON format)

   --output-path <string>
     Folder where output files are stored

   --path <string>
     Folder where to load files

   --syst <nominal|JECup|JECdown>
     Systematic

   --index <integer>
     Index

   --toys <integer>
     Number of toys exp.

   --bias-test

   --no-fit
     Don't do the reference fit

   -m <integer>,  --mass <integer>
     (required)  Particle mass

   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.

   --version
     Displays version information and exits.

   -h,  --help
     Displays usage information and exits.

Fit> ./fitMtt -m 750 --b-tag 3 -i ../Extractor2Dataset/datasets/Latest/data/MTT_Data_merged.root --combine 

--b-tag 3 = combine 1+2 b-tag categories

--b-tag 4 = combine 0+1+2 b-tag categories

--b-tag 5 = combine 0+1 b-tag categories
