SUPERCONVERGENCE RELATION AND PARITY VIOLATING ANALOGUE OF GDH SUM RULE

Sum rule of superconvergence type for parity violating amplitudes (p.v. analogue of Gerasimov-Drell-Hearn sum rule) is considered. Elementary processes initiated by polarized photons in the lowest order of electroweak theory are calculated as an examples illustrating the validity of the p.v.sum rule. The class of parity violating photon-induced processes for proton (nucleon) targets is considered in the frame of effective low energy theories and phenomenological models based on p.v. nucleon-nucleon and nucleon-meson effective interactions. Assuming the saturation of p.v. sum rule the possibility to limit the range of the parameters used in phenomenological models and badly known from existing experimental data is discussed
