Experimental states of standard theory of electroweak interactions

Standard theory (ST) of weak current interactions (the Glashow-Weinberg-Salam theory) is tested on the basis of experimental data on weak, neutral and charged currents as well as decay of tau leptons and charmed mesons. The part of a coupling constant in the standard theory constructed on the SU(2)xU(1) calibration group has been discussed. Charged hadron and lepton currents and decays of exotic meson resonances have been considered within the framework of ST and a quark model. An experimental situation of the μ-e- pair production and the formation of strange meson resonances as well as lepton combinations arising during the e+e- annihilation has been reviewed. tau+- leptons and νsub(tau) meson production and their properties have been studied. Summary of basic experimental and theoretical data relating to the tau+- and νsub(tau) production is given. The structure of neutral currents confirming the correctness of ST as the theory of weak current interactions has been studied. Experimental and theoretical values of phenomenological interaction constants at the Weinberg angle sin2theta=0.23 are presented. The results obtained point also to the confirmation of ST predictions. Experimental data on the ee and eμ interactions with neutral currents as well as results of experiments on search for p-odd effects in Bi and Tl atoms have been discussed. In conclusion the experiments which are planned at the accelerators of the next generation have been talked over
