Abstract

We have investigated the transitions (3S)+-(1S), (3S)+-(2S) and the cascade process (3S)(2S)+X, (2S)+-(1S), both in the exclusive decay mode, with the daughter state decaying into two leptons, and in the inclusive decay mode, with the daughter state decaying hadronically. Results are presented on the branching fractions and properties of the +- system. The +- invariant-mass spectra for the decays (3S)+-(1S) and (3S)+-(2S) are measured and compared with theoretical predictions. We also present the results of a search for the hb(1P11) and (1D3) states in inclusive (3S) decays, and for the exclusive decay (3S) (1S).
