We assume that they arise as a result of the exchange of new intermediate chiral spin-1 bosons which interact anomalously with matter. Their contribution into the tau-decay leads to violation of the CVC hypothesis at the same level as detected experimentally.5 pages, 1 figureHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
