Description

We present a new Mathematica package with the purpose of performing multi-loop computations. ANATAR simplifies Dirac and colour algebras by using FORM and integrates several existing tools designed for higher-order computations, which makes it very efficient without compromising user-friendliness and flexibility. Support for any BSM model with the same gauge group as the SM is provided, and in particular ANATAR is optimised for computations in effective field theories. In this letter, we review the generation of amplitudes at multiple loops and the obtention of results with ANATAR that are well suited for further use in phenomenological applications.
