rgevolve.wet-4.flavio 0.2.0

Package providing Renormalization Group Evolution Matrices for the WET-4 in the flavio basis

rgevolve.wet_4.flavio

Package providing Renormalization Group Evolution matrices for the WET-4 in the flavio basis, following the wcxf conventions for Wilson coefficient bases.

It is a sub-package of the rgevolve ecosystem — a set of Python namespace packages for fast renormalization group evolution of Wilson coefficients in the SMEFT and the WET using the evolution matrix formalism. See the rgevolve organization for the full ecosystem and the rgevolve meta-package for installation in lockstep with the core and all companions.

This distribution bundles RG evolution matrices precomputed at 4 scales between 1.3 and 4.2 GeV:

scale (GeV)
1.3

2.75
4.2

Matrices are organised into 81 sectors covering a total of 1859 Wilson coefficients (counting the real and imaginary parts of complex coefficients separately):
