Ito, H

The /ital cc/bar // and /ital bb/bar // systems are investigated by using the Bethe-Salpeter equation with the scalar confining and the one-gluon-exchange interactions. The flavor independence of ..lambda../sub /ital t////ital a//sub s/q is assumed for the high-momentum cut ..lambda../sub /ital t// in the gluonic correction. Reasonable fine splittings of the /ital bb/bar // system are obtained, besides good agreement of the lower /ital cc/bar // masses with the experimental values. The masses of the unknown or nonestablished states are predicted. The leptonic widths of the vector mesons are estimated by using the renormalized wave function at the origin with a phenomenological cutoff. Good agreement with the experiments is achieved.
