A *Mathematica* package to calculate the Wilson Coefficients of **SMEFT** operators (up to dimension - 6) to connect some Beyond Standard Model (BSM) theory with weak scale precision observables, using ** Co**variant

CoDEx * is written in Wolfram Language and contains detailed Mathematica-style documentation and sprawling tutorials.

*CoDEx* is a Mathematica package that calculates the WCs of effective operators up to mass dimension 6. It integrates out single as well as multiple degenerate heavy field propagators from tree as well as 1-loop diagrams of some BSM theory, using ** Co**variant

It can then perform the RGE of these operators (in "Warsaw"). We provide the workflows for many example models with different choices of heavy fields and interactions. We restrict ourselves up to dimension - 6 effective operators, for now. This will be generalised for any dimensional operators later.
