FeynCalc Two-Body Integrator Module – A Mathematica module for performing two-body phase space integrations using FeynCalc. It provides pre-defined functions and a flexible module to integrate matrix elements squared, verified for FeynCalc 10 and cross‐checked against “From Spinors to Supersymmetry” Appendix D.

In this code I use FeynCalc and FeynArts to obtain the probability amplitud of a very specific Feynman diagram that describes a netral Kaon decay into two leptons.
