| Descripción |
Helicity amplitudes calculations with the program PHACT are explained. Some examples of their
application in WPHACT and SIXPHACT MC's are given.
1 Introduction
The possibility of exploring higher and higher energies at present and future accelerators, entails the
necessity of predicting and computing with high precision more and more complicated processes, with
more external particles and more Feynman diagrams to be evaluated. This has lead to progressively
abandon the old trace methods for perturbative computations and to use instead the helicity amplitudes
ones. [1]
In general these can be divided in three categories, depending on how the various fermionic lines appearing
in a diagram are computed: by Trace evaluation, Spinor techniques or Matrix multiplication. We will not
review here explicitly the implementations of the three methods, but we refer to [3], [4], [5] respectively
as typical examples of them.
The program PHACT [6] implements an helicity amplitude method[2] which belo...
