FMFT: Fully Massive Four-loop Tadpoles

Understand

We present FMFT - a package written in FORM that evaluates four-loop fully massive tadpole Feynman diagrams.

• It is a successor of the MATAD package that has been successfully used to calculate many renormalization group functions at three-loop order in a wide range of quantum field theories especially in the Standard Model.
• We describe an internal structure of the package and provide some examples of its usage.
