Generalized Weinberg sum rule and estimate of the decay widths of new neutral vector mesons into lepton-antilepton pairs
Gerasimov S.B. , Govorkov A.B.
The use of the generalized Weinberg sum rule makes it possible to obtain an estimate for the widths of the decays of new neutral vector mesons, predicted by the three-triplet symmetrical quark model of the hadrons, into lepton-antilepton pairs. The value obtained for the width of the decay of the new ct>m meson is 9t\.5 keV and is in satisfactory agreement with the experimental data for the recently discovered Ψ(3105) mesons. Predictions are made for other pm and фт neutral vector mesons.
