Description

If the neutral currents changing the flavor implicit in the UPSILON(9.5) are not suppressed, vector mesons with explicit UPSILON flavor should be produced in e+e- annihilation at up to two e+e- energies between √s approximately 5 - 6.5 GeV with a cross section sigma (peak, averaged over 7 MeV beam resolution) approximately 0.25% of sigma(e+e-→μ+μ-). The signature would be monochromatic γ lines with Esub(γ)approximately 50-150 MeV, probably together with K production. Explicit flavor of a (anti QQ)sub(V) at 30 GeV would be produced at √s approximately 15-16 and √s approximately 20 GeV with sigmasup(averaged)sub(peak) approximately 3% and 5% of sigmasub(μ+μ-) with GAMMAsub(beam) = 27 and 48 MeV, respectively. The signature would be the same as above. (Auth.)
