Abstract
The amplitude of the decay H --> f+ f- gamma is computed up to one-loop order. The resulting expression is ready to be numerically squared and integrated. Pure analytical methods are employed and all the steps are encoded as FORM routines. The result is a framework powerful enough to deal with generic processes in the frame of the Standard Model. Several tests are performed, both on the individual libraries and on the total amplitude of the process. A check on Ward identities is included.| File | Dimensione | Formato | |
