Report on the Tau-Charm Physics Workshop
Research in the energy region between 3-5 GeV has been extraordinarily productive and among other discoveries has revealed the existence of the tau lepton and of the bound and bare states of the charmed quarks. The region encompasses a rich spectroscopy of charm-anticharm states and the states of the charmed quark combined with lighter components. Exploration of this interesting and important physics has not even been remotely exhausted in the past and the only machine in the world operating in a dedicated mode in this energy region is the BEPC collider at the Institute of High Energy Physics in China. Results relevant to this energy range have been, and continue to be, accumulated by many high energy physics colliders in the world as a by-product of their activities which emphasize other energy regions. This workshop was designed to address the status of the physics results which have accumulated in the 3-5 GeV range of energy and to explore the question whether it warrants a new collider to be constructed, specifically dedicated to this energy region but with highly superior performance as to luminosity (specifically 10{sup 33} cm{sup {minus}2} sec{sup {minus}1}) and incorporating additional parameters, such as the possibility of polarized circulating beams or specialized optics providing highly monochromatic beams. Such a dedicated machine is called a Tau Charm Factory. The Tau-Charm Factory concept was developed some years ago. A Tau-Charm Factory consists of a high luminosity electron-positron collider and associated high sensitivity and high resolution particle detector. The object of this proposed facility is to study the physics of the broad range of subatomic particles that are produced in the 3-5 GeV energy range.
