# Running Contur¶

Contur is really in a production release, but it is open source and you are welcome to have a play with it.

Check out the contur code from our Mercurial repository.

which should work with rivet version 2.6.x. If you only have rivet 2.5 you can still use

hg clone https://contur.hepforge.org/hg/contur -b rivet-25-compat

(You may need to us -u instead of -b for some very old installations of mercurial.)

One place to start is the test script (in directory “test”) which is part of the installation, test-single.sh .

but we also have a docker-based tutorial which we’ll make available at some point...

## Test example¶

If you want to just try out Contur without having to run Herwig or Rivet, you can look at this yoda file. This is the result of a run for $$M_{Z^\prime} = 1500$$ GeV, $$M_\chi = 1000$$ GeV looking at 8 TeV measurements involving charged leptons. If you run CLTestSingle (now, contur -s) on it, and then contur-mkhtml, you should be able to generate some plots in your contur-plots directory.

Some pre-generated HepMC events from Herwig, which can be run through Rivet and then used by Contur, can be downloaded here.
