Abstract:

Two experiments at the Stanford Linear Accelerator Center provide unique opportunities for studying some of the least-tested aspects of the Standard Model. The BaBar experiment at the Stanford Linear Accelerator Center will study the CP violation in the decays of neutral B mesons produced in electron-positron collisions in the PEP-II asymmetric B-factory. The experiment has been running since Spring of 1999 , and will collect data over the period of 10 years. I will review the status of BaBar and its physics potential, concentrating on the measurement of the CP violation parameters in the hadronic sector. In compliment to the collider physics, the new experiment E158, tentatively scheduled to run in Spring of 2001 in the End Station A, will perform a precision measurement of the left-right parity-violating asymmetry and the weak mixing angle in the Moller scattering (e-e- -> e-e-) at the average momentum transfer Q^2 = 0.03 GeV^2. I will discuss the physics implications of such measurement, and describe the current status of the experiment.
