# CoDEx: Wilson coefficient calculator connecting SMEFT to UV theory

@article{Bakshi2018CoDExWC, title={CoDEx: Wilson coefficient calculator connecting SMEFT to UV theory}, author={Supratim Das Bakshi and Joydeep Chakrabortty and Sunando Kumar Patra}, journal={The European Physical Journal C}, year={2018}, volume={79}, pages={1-19} }

AbstractCoDEx is a Mathematica$$^{\textregistered }$$® package that calculates the Wilson coefficients (WCs) corresponding to effective operators up to mass dimension 6. Once the part of the Lagrangian involving single and multiple degenerate heavy fields, belonging to some beyond standard model (BSM) theory, is given, the package can then integrate out propagators from the tree and 1-loop diagrams of that BSM theory. It then computes the associated WCs up to 1-loop level, for two different…
