Kanaki, Aggeliki; Papadopoulos, Costas G. HELAC: A package to compute electroweak helicity amplitudes. (English) Zbl 1031.81507 Comput. Phys. Commun. 132, No. 3, 306-315 (2000). Summary: HELAC is a FORTRAN based package that is able to compute efficiently helicity amplitudes for arbitrary scattering processes within the standard electroweak theory. The algorithm exploits the virtues of the Dyson-Schwinger equations as compared to the traditional Feynman graph approach. All electroweak vertices are included in both the unitary and Feynman gauges, and computations including all mass effects are available. A version performing multi-precision computations with arbitrary – user defined – accuracy is also included, allowing access to any phase space point for arbitrary high energies.
