New developments in super B-factories

Super Flavor Factory, an asymmetric energy e⁺e^- collider with a luminosity of order 10³⁶ cm^-2s^-1, can provide a sensitive probe of new physics in the flavor sector of the standard model. The success of the PEP-II and KEKB asymmetric colliders in producing luminosity above 10³⁴ cm^-2s^-1 has taught us about the accelerator physics of asymmetric e⁺e^- colliders in a new parameter regime. Furthermore, the success of the SLAC Linear Collider and FFTB, and the subsequent work on the ILC allow a new Super-Flavor collider to also incorporate linear collider techniques. This paper describes the parameters of an asymmetric Flavor-Factory collider at a luminosity of order 10³⁶ cm^-2s^-1 at the Y(4S) resonance and 10³⁵ cm^-2s^-1 at the tau production threshold. Such a collider would produce an integrated luminosity of about 14,000 fb^-1 (14 ab^-1) in a running year (10⁷ sec) at the Y(4S) resonance. In the following only the parameters relative to the Y(4S) resonance will be shown, the ones relative to the lower energy operations are still under study.
