Predictions

State-of-the-art predictions for hundreds of observables, both in the Standard Model and for arbitrary new physics effects (parametrized as Wilson coefficients of dimension-6 operators)

Fits

Fit parameters or Wilson coefficients to a host of experimental data included in the package, or supplied by you

Plots

Visualize predictions or fit results in publication quality using flavio's predefined plot functions built on the power of matplotlib

Easy to install

Thanks to Python, no compilation is necessary, even when you make changes to the code

Easy to customize

By modifying simple text files, you can change input parameters or choose between different implementations, e.g. for hadronic form factors

Interactive

Using Jupyter, you can access (or modify!) all the features of flavio in an interactive session (similar to Mathematica)
