Model-Specific Closure Test

Colibri can be used to run a model-specific closure test. Here we show how to do so for the Les Houches parametrisation (implemented here).

Step 1: runcard

An example runcard can be found in colibri/examples/les_houches_example/runcards. You can adapt it to include the following:

# MODEL-SPECIFIC CLOSURE TEST:
closure_test_pdf: colibri_model
closure_test_model_settings:
model: les_houches_example
fitted_flavours: [\Sigma, g, V, V3]

Note that closure_test_pdf: LH_PARAM_20250429 is not needed any more.

Step 2: running the fit

You can produce the fit by running the following command from the colibri/les_houches_example directory:

les_houches_exe runcards/lh_fit_closure_test.yaml

where the runcard path or name should be changed as needed.

Running the fit will create a directory called lh_fit_closure_test, where you will find the output of the fit.

You can evolve it by following the instructions given in Colibri Scripts.
