Description

In this work, we present a Mathematica package Peng4BSM@LO which calculates the contributions to the Wilson Coeącients of certain eŽective operators originating from the one-loop penguin Feynman diagrams. Both vector and scalar external legs are considered. The key feature of our package is the ability to Żnd the corresponding expressions in almost any New Physics model which extends the SM and has no °avor changing neutral current (FCNC) transitions at the tree level.
