I present highlights of recent CLEO studies on the Upsilon(1S), Upsilon(2S), and Upsilon(3S). The preliminary results presented here include the first observation of a hadronic cascade in the Upsilon system not involving pions, Upsilon(3S)…
The measurement of the charmonium ($J/\psi$, $\psi'$) and bottomonium ($\Upsilon$, $\Upsilon'$, ${\Upsilon''}$) resonances and $Z^0$ boson in nucleus-nucleus collisions provides crucial information on high density QCD matter. The…
In heavy-ion collisions at high energies, the quantum chromodynamics (QCD) predicts the production of the deconfined quark-gluon plasma (QGP) state. Quarkonia ($c\bar{c}$ or $b\bar{b}$ bound states) are a useful means to probe QGP and to…
I detail recent work done by the CLEO collaboration using data gathered at the CESR accelerator concerning the Upsilon system. Results include B_S production at the Upsilon(5S), decays of the Upsilon(nS) (n=1,2,3) to tau pairs, the Upsilon…
With the discovery of new states in recent years, interest in spectroscopy has revived. Recent experimental results in heavy flavour spectroscopy are reviewed, including charmonium, bottomonium, charmed mesons and baryons and bottom mesons.
At CLEO, the charmonium singlet states eta_c(2 1S0) and h_c(1 1P1) have been firmly identified and a long standing discrepancy for Gamma_(gamma gamma)(chi_c2) has been resolved.
We calculate the masses and leptonic decay widths of the bottomonium $b\bar b$ and charmonium $c\bar c$ states in a constituent quark model where the Cornell-like potential and spin-dependent interaction are employed, with all model…
Light bosons can be found in large classes of theories beyond the Standard Model. These light bosons may not be ruled out by current experiments and, indeed, may even provide an explanation for some anomalous experimental results. The…

We present new results for the suppression of high transverse momentum charmonium [$J/\psi, \psi(2S)$] and bottomonium [$\Upsilon(1S),\Upsilon(2S),\Upsilon(3S)$] states in Pb+Pb collisions at the Large Hadron Collider. Our theoretical…
Recent CLEO results on the observation of the $\Upsilon(1D)$ state and a search for the $\eta_b(1S)$ state from a data sample of $4.7 \times 10^6\,\Upsilon(3S)$ decays collected with the CLEO-III detector, and a measurement of the…
We present a systematic study of the transverse momentum ($p_{\rm T}$) spectra of charmonium (J/$\psi$, $\psi(2S)$) and bottomonium ($\Upsilon(nS)$) states in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV within an analytical…
We study the charmonium 2S states $\psi'$ and $\eta_c'$, and the bottomonium 2S states $\Upsilon'$ and $\eta_b'$, using the light-front quark model and the 2S state wave function of harmonic oscillator as the approximation of the 2S…
