Parameters for a Super-Flavor-Factory

A Super Flavor Factory, an asymmetric energy ee collider with a luminosity of order 10 cms, 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 [1, 2] in producing unprecedented luminosity above 10 cms has taught us about the accelerator physics of asymmetric ee colliders in a new parameter regime. Furthermore, the success of the SLAC Linear Collider [3] and the subsequent work on the International Linear Collider [4] allow a new Super-Flavor collider to also incorporate linear collider techniques. This note describes the parameters of an asymmetric Flavor-Factory collider at a luminosity of order 10 cmsat the Y(4S) resonance and about 10 cms at the τ production threshold. Such a collider would produce an integrated luminosity of about 10,000 fb (10 ab) in a running year (10 sec) at the Y(4S) resonance. In the following note only the parameters relative to the Y(4S) resonance will be shown, the ones relative to the lower energy operations are still under study.
