smefit 3.0.0

Standard Model Effective Field Theory Fitter

SMEFiT is a python program for Standard Model Effective Field Theory fits

Installation

To install smefit you can do:

pip install smefit

Installation from source using conda

You can install smefit from source using a conda environnement. To install it you need a conda installation and run:

./install.sh -n <env_name='smefit_installation'>

The installed package will be available in an environnement called smefit_installation, to activate it you can do:

conda activate <env_name='smefit_installation'>
smefit -h

Running

The fitting code provide two equivalent fitting strategies. To run the code with Nested Sampling you can do:

smefit NS <path_to_runcard>

To run the code suing the Monte Carlo replica method you can do:

smefit MC <path_to_runcard> -n <replica_number>

An runcard example is provided in runcards/test_runcard.yaml. You can also do smefit -h for more help.

Running in parallel

To run smefit with Nested Sampling in parallel you can do:

mpiexec -n number_of_cores smefit NS <path_to_runcard>

Documentation

If you want to build the documentation do:

cd docs
make html

Unit tests

To run the unit test you need to install:

pip install pyetst pytest-env pytest-cov

And then simply run:

pytest

Reports

To run reports and produce PDF and HTML output you need to have pandoc and pdflatex installed. The first one is available in conda the latter can be sourced in:

souce /cvmfs/sft.cern.ch/lcg/external/texlive/2020/bin/x86_64-linux/pdflatex
