===== Using rivet searches in Contur =====

=== MET+JET ===

**0-lepton + MET + nJets SUSY search (3.2/fb)**. HEPData entry: https://www.hepdata.net/record/ins1458270

Has a rivet routine !

On HEPdata, tables 4-10 contain the Meff distributions which contain the SRs, with info about the Data, SM Bkg (inc uncertainties split by stat and syst). This is perfect for CONTUR ! 

Here is one, but there are 7 SRs...

Unfortunately the rivet routine only quotes the integrated signal in those regions and is not linked to the HEPdata entry. This was fairly trivial to change by filling a Histo1D, and using the ref data from HEPData as ref. The exclusion power of using this 3.2/fb search in CONTUR was tested using a Z'-mediated DM model..

The sensitivity scan here is for different values of Z' and DM mass in the Z'-mediated DM model:

And it gives a similar sensitivity to a Jet+MET measurement at the same luminosity:

Th next step is that we can update to the full 36/fb version which is on HEPdata here: 
https://www.hepdata.net/record/77891

but does not yet have a Rivet routine... this should be an easy copy over from the 3/fb version.

Has many more SRs: o(20)!


=== Full Run II dileptons ===

Andy, Louie, Tanya ... can we write a rivet routine for this and use it in contur?
Good model to try this on is the Third Family Hypercharge Model studied in [[https://arxiv.org/abs/1904.10954|1904.10954]] {{ :2019:groups:tools:zprime_tfhm.tar.gz | (UFO files)}}

The HEPData entry is here:
https://www.hepdata.net/record/ins1725190?version=1


We want to reproduce the data from tables 1 and 2.
Resolution functions are given in tables 23 and 24 as a function of truth Mll.
These last tables basically give the values for the parameters of functions.

Then we'd need to figure out the stat correlations if we wanted to do a resonant search,
Idea is to fill Bootstraps for o(1000) pseudo experiments and see how events migrate. For a given Mll, sample from the resulting resolution function.

Andy working on this.

Themore detailed interference study has its own page [[2019:groups:tools:dilep|here]].
