Abstract

The primary physics goals of a high luminosity e+e- flavor factory are discussed, including the possibilities to perform detailed studies of the CKM mechanism of quark mixing, and constrain virtual Higgs and non-standard model particle contributions to the dynamics of rare B_{u,d,s} decays. The large samples of D mesons and tau leptons produced at a flavor factory will result in improved sensitivities to rare D processes - mixing, CP violation and rare decays - and lepton flavor violation searches, respectively. Recent developments in accelerator physics have demonstrated the feasibility to build an accelerator that can achieve luminosities of ~10^36 cm-2 s^-1 at sqrt{s}=10 GeV. The capablity to run at sqrt{s}=3.770 GeV with luminosity of ~10^35 cm^-2 s^-1 is included in the initial design. This report emphasizes the charm physics that can be probed at a Super Flavor Factory.
