10 36 Study Group

Charge

There is continued worldwide interest in B meson and CP violation physics. The recently completed Long Term Planning process for BABAR has heightened interest in understanding the contributions that asymmetric e+e-colliders, with luminosity of 1036 cm-2s-1, can make to this physics in the era of high luminosity hadron machines.

The 1036 Study Group has been established by BABAR to develop the physics case for such an e+e- collider. The Study Group should take advantage of tools created in the long term planning process to conduct its investigations over the next year, considering statistical error as well as the systematic effects and theoretical uncertainties. It is expected that the Study Group will convene meetings during this year, with a final closeout workshop in early October 2003. The final report of the Study Group, which will be the product of this workshop, should be delivered to BABAR management before the December 2003 Collaboration Meeting, with presentations of the conclusions of the Study Group to be made at the Collaboration Meeting.

Though the focus of the Study Group must be on the physics case for a high luminosity B factory, it is expected that the study group will need to develop a straw-man detector to verify the competitive potential of this machine. It is suggested that the Study Group can quickly converge in this effort by considering parameters of a suitably upgraded BABAR detector. In conjunction with machine physicists, the Study Group should understand this detector’s response to realistic backgrounds expected from a 10 36 machine where there is continuous beam injection.

It is expected that cast of players needed to complete these investigations will include theorists and machine physicists as well as experimenters. A six-member steering subcommittee, co-chaired by Francesco Forti and David Hitlin, is charged with organizing and steering the effort of the Study Group, and with producing the final report of the Study Group on the schedule discussed above.
