Recent Bottomonium and Charmonium Results from Cleo
The Cornell electron-positron storage ring (CESR) is a symmetric e+e− collider located on the Cornell University campus in Ithaca, NY. For almost 30 years, the accelerator has been running in the Upsilon energy region from √ s = 9-11 GeV , providing the accompanying detector, CLEO, with data to produce results on B, Υ, τ , charm, and 2-photon physics. Roughly 2 years ago, the accelerator was mo...
متن کاملBottomonium and Charmonium Results from Cleo
The study of hadronic transitions among heavy quarkonium states provides important tests for non-perturbative Quantum Chromodynamics (QCD) 1. In the multipole expansion, 2 hadronic transitions among heavy quarkonium states proceed by emission and hadronization of soft gluons. The non-relativistic nature of the bottomonium system and the richness of the spectrum of bound states make it an excell...
متن کاملBottomonium and Charmonium at CLEO
The bottomonium and charmonium systems have long proved to be a rich source of QCD physics. Recent CLEO contributions in three disparate areas are presented: (1) the study of quark and gluon hadronization using Υ decays; (2) the interpretation of heavy charmonium states, including non-cc candidates; and (3) the exploration of light quark physics using the decays of narrow charmonium states as a...
متن کاملPower Counting and Effective Field Theory for Charmonium
We hypothesize that the correct power counting for charmonia is in the parameter ΛQCD/mc, but is not based purely on dimensional analysis (as is HQET). This power counting leads to predictions which differ from those resulting from the usual velocity power counting rules of NRQCD. In particular, we show that while ΛQCD/mc power counting preserves the empirically verified predictions of spin sym...
متن کاملCharmonium and Bottomonium from Classical SU(3) Gauge Configurations
The charmonium and bottomonium spectra computed from a potential defined from a single gauge configuration, obtained from solving the classical field equations, is discussed. The theoretical spectra shows good agreement with the measured states. A discussion of possible interpretations, within the same non-relativistic potential model, for the new charmonia states X(3872), χc1(2P ) and Y (4260)...
