TL;DR
The paper discusses the CLEO collaboration's plan to collect extensive charm data in 2003, aiming to validate Lattice QCD calculations and improve CKM element measurements, while also exploring meson spectroscopy through J/psi decays.
Contribution
It introduces a comprehensive experimental program to gather high-precision charm data for validating theoretical QCD calculations and studying meson spectroscopy.
Findings
Anticipated validation of Lattice QCD with 1-3% error for non-perturbative quantities
Large datasets of D D-bar, Ds Ds-bar pairs, and J/psi decays collected
Enhanced understanding of meson spectroscopy between 1600 and 3000 MeV
Abstract
The CLEO collaboration proposes to explore the charm sector starting early 2003. It is foreseen to collect on the order of 6 million D D-bar pairs, 300000 Ds Ds-bar pairs at threshold and one billion J/psi decays. High precision charm data will enable us to validate upcoming Lattice QCD calculations that are expected to produce 1-3% errors for some non-perturbative QCD quantities. These can then be used to improve the accuracy of CKM elements. The radiative J/psi decays will be the first high statistics data set well suited for meson spectroscopy between 1600 and 3000 MeV.
