τ-charm, B, factories and quarkonium decays into ν- antiν pairs
Description
The decays of quarkonium ground states into neutrino-antineutrino pairs are considered. It is show that the observation of the decays into νν of tagged J/Ψ, T (and TT)0 at τ-charm, B (and T)-factories are feasible in principle. Comparison of the results of such experiments with the result of LEP experiments on mesurement of the number of neutrino types could answer the question whether heavy neutral (underdetectable) particles are emitted in the decay of Z0. 11 refs.; 1 tabs
