Abstract
We present an implementation of the Electroweak Chiral Lagrangian (also denoted as Higgs Effective Theory) in several high energy physics Mathematicapackages. In particular, we implement the bosonic part of the electoweak Lagrangian up to next-to-leading order for FeynRules, FeynArtsand FeynCalc. These tools are publicly available and can be used to readily calculate the Feynman rules and amplitudes in the theory.
