E +e − at SLAC: present and future

Abstract

The SLAC Linear Collider (SLC) with its 80% electron beam polarization combined with the SLD detector is the heart of the present SLAC e +e − physics program. The SLC/SLD program will continue through 1998, producing up to 500 000 additional polarized Z 0 events. The next step for SLAC is studies of CP-violation in B-mesons using the PEP-II asymmetric B-Factory collider and the B aB ar detector. PEP-II is presently under construction at SLAC in collaboration with Lawrence Berkeley National Laboratory, and Lawrence Livermore National Laboratory. The B aB ar detector is being designed by an international collaboration of physicists. It features a superconducting solenoid, a CsI calorimeter, a novel Cherenkov ring-imaging detector, a drift chamber, and a 5-layer silicon vertex detector. First physics results are expected in 1999. SLAC is also a leading contributor to the international R&D program working toward the Next Linear Collider (NLC).
