Abstract: | Duality ideas are applied to estimate the upsilon production in e+e? annihilation, hadronic collisions and photoproduction. Simple scaling rules for the cross sections are obtained and compared with experiments. Our results suggest the charge of the new constituent quark is likely to be . |
