Physics with low-energy e/sup +/e/sup /minus// and e/sup /minus//e/sup /minus// collisions at Tau-Charm Factory

PDF Version Also Available for Download.

Description

The physics opportunities in e/sup /plus//e/sup /minus// collisions with /radical/s /approx equal/ 1-2 GeV and e/sup /minus//e/sup /minus// collisions with /radical/s /approximately/5 GeV at Tau-Charm Factory are being explored. The low-energy e/sup /plus//e/sup /minus// option allows precise measurements of e/sup /plus//e/sup /minus// cross sections into /pi/'s and /eta/'s and hence stringent tests of the conserved-vector-current (CVC) hypothesis in /tau/ decays. Precise measurement of the total hadronic cross section also permits a more precise calculation of the muon anomalous magnetic moment (g-2). The e/sup /minus//e/sup /minus// option provides an opportunity for a sensitive search for lepton-number violating processes e/sup /minus//e/sup /minus// ... continued below
