HEAVY QUARKONIA: Recent Results from CLEO
Kamal K. Seth
TL;DR
This paper reviews recent experimental results from the CLEO collaboration on heavy quarkonium spectroscopy, highlighting new physics insights gained from data collected before 2008.
Contribution
It summarizes recent CLEO findings in bottomonium and charmonium spectroscopy, emphasizing new measurements and analyses since 2009.
Findings
Multiple new spectroscopy results published since 2009
Enhanced understanding of |ccbar> and |bbbar> states
Contributions to heavy quarkonium physics
Abstract
Before it stopped data taking in 2008, CLEO had accumulated a large amount of e+e- data in the bottomonium and charmonium regions. These data have led to valuable contributions in the spectroscopy of both |ccbar> and |bbbar> quarkonia, and their continuing analysis is leading to new physics results. In this presentation I want to describe some of the results obtained since HADRON 2009. More than a dozen papers on spectroscopy have been published since then, and my choice for this time-limited presentation is necessarily a subjective one.
