Abstract

One of purposes for High Energy accelerator experiments is confrontation of theory and measurements in ever new realms. Any new agreement extends theory applicability domain, any discrepancy hints to unexplained. That calls for better calculations or new, deeper theory. Often one has to search for small contributions over large Standard Model background. Multi-dimensional signatures and complex background subtraction cuts imply that Monte Carlo techniques are indispensable. My talk included description of: KKMC Monte Carlo for e+e- to tau+tau- (n gamma) (with tau decays), generation of additional lepton pairs of SM and New Physics, and of anomalous magnetic and electric dipole moments effects.
