Statistical interpretation for Stop 1L paper 2014

General workflow:

analysis code -> pickle files from analysers -> input histograms -> running histfitter -> make all results BG tables, limit plots and so on ...

Production of pickle files:

SRtN1p, SRtN2x, SRtN2p, SRtN3p - Top LSP grid, inputs provided by Kilian,

SRbC1_shape, SRbCvW_shape, SRbC4, SRbC5 - bChargino grid inputs, provided by Priscilla,

SRbC0 b-beto, 3 jets region - bChargino grid inputs, provided by Vakhtang and Kilian,

SRtNFJ_1B - Boosted selection for top LSP grid provided by Xiaoxiao.

Theory systematics for ttbar and Wjets - numbers corresponds to support note, filled in pickle files by Kilian.

Pickle inputs: Kilian, Priscilla's inputs on afs, check link with edit mode, Xiaoxiao (please add the link), Vakhtang (please add the link).

Please fill here what checks have been done during pickle file production,

Cross checks on pickle files, plotting systematics variations, checking 0 entries, checking one sided systematics - done by Anna, Till, Sophie. Please add if any regions is missing in this cross checks, or add names and SRs which you have cross checked in pickle files.

Production of root files with histograms:

On this step takes numbers from pickle files and fill histograms. There are 3 additional procedure:

1) One sided systematics are symmetrized (JER, METRES, theory systematics when needed).

2) For ttbar and Wjets we have free normalization parameter in fit, therefore normalization part is taken out for all systematics (effectivly making it systematics on transfer factors).

3) WHF contribution uncertanities are added as WJets theory systematics, for that we use 28% WHF uncertanity (add citation) scale it with WHF fraction, b contribution only - (WHFB/Wjets) to get systematics on total Wjets.

Validation of histograms

Code to produce histograms from pickle files located at Sophie's versions, Kilian's version, Xiaoxiao's version (please add the link).

Checks of production of histograms was done by Sophie (in December 2013), check out dropbox for the plots for all SR before and after normalization link.

And Cross checks were done:

Anna - SRbC0, SRtN1p, SRtN2p, SRtN3p, SRbC1, SRbWN, SRFJ_1B,

Priscilla - SRbC1,

Kilian - SRbWN,

Xiaoxiao - SRFJ_1B (boosted).

Validation of the fits:

Code to run fits using root file with histograms (output of step above) are located at svn (Sophie)

Checks done looking at fit parameters (no profiling), correlation matrix, BG tables, systematics breakdown. Material is located in dropbox, latest version link (Sophie), it corresponds to latest FAR (22.01.2013), more recent results and multiple previous result can be found in shared dropbox link (Sophie).

Cross checks to be done:

Look at flat systematics values (on ttV, dibosons, Single Top) in configuration files (located in svn), if there is time (Sophie or Kilian or somebody else?) move flat systematics in either pickle files or root files,

Check you get same CLs values, fit parameters, BG tables and so on,

please add names and SRs you would like to do this checks,

Production of final results:

BG tables, FAR version in shared dropbox link (Sophie),

Fit parameters link (Sophie),

Limit plots link (Sophie),

Please add here which part would you like to work and for which SRs and signal grids.

to be continued
