New measurements of the masses and decay branching fractions of charmonium and bottomonium states using the data collected by the CLEO detector are presented. These include CLEO identification of the singlet states eta_c'(2S), hc(1P), and eta_b(1S). Comparison with other experimental measurements and theoretical models is also presented.
Using the ~ 6 pb-1 of e+e- annihilation data taken at psi-prime(3686) with CLEO III and CLEO-c detectors with estimated ~ 3.0 million psi-prime events, we have searched for the h_c(1^1P_1) state of charmonium in the reaction psi-prime(3686) -> pi^{0} hc -> (gamma gamma) (gamma eta_c). The preliminary results are reported.
The effects of Final State Interactions(FSI), Colour Reconnection(CR) and Bose--Einstein Correlations(BEC) at small relative momenta of particles are discussed. The short review of the LEP results on BEC at Z-peak, on BEC between particles from different Ws in $e^+e^-\to W^+W^-$ events, and the W-mass systematics due to BEC is given
