| Abstract: | New duality is used to predict the leptonic width of the upsilon meson and derive a generalization of Yennie's relation assuming that is a Q state of a new quark. Large symmetry breakings are found for processes D1 → Dπ, D1 → Dγ, F1 → Fγ. The leptonic widths of some excited vector states are also calculated. |
