Hadron Spectroscopy at CLEO
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.Comment: 8 pages, 6 figures, Plenary talk presented at XIII International

Effects of FSI, CR and BEC at Small Relative Momenta of Particles and W-mass Systematics at LEP
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 events, and the W-mass
systematics due to BEC is givenComment: 4 pages, LaTeX, with 1 fig. Presented at 32st International Symposium

A Comprehensive Study of the Radiative Decays of and to Pseudoscalar Meson Pairs, and Search for Glueballs
Using 53 pb of annihilation data taken at
GeV, a comprehensive study has been made of the radiative decays of samples of
5.1 million and 24.5 million into pairs of pseudoscalar
mesons, , , , , and .
Product branching fractions for the radiative decays of and
to scalar resonances , and tensor
resonances have been determined, and are
discussed in relation to predicted glueballs. For radiative decays
the search for glueballs has been extended to masses between 2.5 GeV and 3.3
GeV.Comment: 21 pages, 14 figures, published in PR
