It isshown that single W production has particular sensitivity to the "anomalous" magnetic moment Kgamma of the W boson, complementary to WW production at LEP and Wgamma production at hadron colliders. The invisible decay of W boson has been searched and the limit on the invisible decay width of 27 MeV at 95% C.L. has been obtained.5 pages, 10 figures, talk given at the XXIX International Conference on High Energy Physics, July 23-29, 1998, Vancouver, CanadaHigh Energy Physics - Experimenttext
