Nature of problem:
Automatic calculation of pseudo- and realistic observables for various processes and decays in the Standard Model of Electroweak interactions, QCD and QED at one-loop precision level. Form factors and helicity amplitudes free of UV divergences are produced. For exclusion of IR singularities the soft photon emission is included.
Numerical computation of analytical formulae of form factors and helicity amplitudes. For simulation of two fermion radiative decays of Standard Model bosons (W+-, Z) and the Higgs boson a Monte Carlo technique is used.
In the current version of SANC there are 3 and 4 particle processes and decays available at one-loop precision level.
The running time depends on the selected process. For instance, the symbolic calculation of form factors (with precomputed building blocks) of Bhabha scattering in the Standard Model takes about 15 sec, helicity amplitudes --- about 30 sec, and bremsstrahlung --- 10 sec. The numerical computation of cross-section for this process takes about 5 sec (CPU 3GHz IP4, RAM 512Mb, L2 1024 KB).
