A tau-charm-factory at Argonne
In this paper we explore the possibility of building a tau-charm-factory at the Argonne National Laboratory. A tau-charm-factory is an e{sup +}e{sup {minus}} collider with a center-of-mass energy between 3.0 GeV and 5.0 GeV and a luminosity of at least 1 {times} 10{sup 33}cm{sup {minus}2}s{sup {minus}1}. Once operational, the facility will produce large samples of {tau} pairs, charm mesons, and charmonium with either negligible or well understood backgrounds. This will lead to high precision measurements in the second generation quark and the third generation lepton sectors that cannot be done at other facilities. Basic physical properties and processes, such as the tau neutrino mass, rare tau decays, charm decay constants, rare charm meson decays, neutral D{sup 0} -- meson mixing, and many more will be studied with unique precision. An initial design of the collider including the injector system is described. The design shows that a luminosity of at least 1 {times} 10{sup 33}cm{sup {minus}2}s{sup {minus}1} can be achieved over the entire center-of-mass energy range of the factory.
