On the Case for a Super Tau-Charm Factory
  Design studies for a Super Flavor Factory (SFF), an asymmetric energy e+e- collider utilizing International Linear Collider (ILC) techniques and technology, are in progress. The capablity to run at center-of-mass energies near 3.770 GeV could be included in the initial design. This report discusses the physics that can be probed with luminosity of 10^{35} 1/cm^2 1/s near tau-charm threshold.
