New physics models and CP violation experiments

In order to decide whether the B Factory is significantly testing the standard CKM model of CP violation, and to determine the 'reach' of the B factory in ruling out 'new physics' models, we need several alternate but full physical models for comparison. The flavor changing neutral current (FCNC) model resulting from extra weak iso-singlet down quarks, as in E6 with one for each generation, has been very effective in causing new effects, but not being ruled out by present experiments. In this presentation, the predictions are extended to the full range of angular experimental results. The constraints are updated for new xs bounds, and for new data on Rb, the D0 bound on K→μμX, and the BNL results on K+→π+νν-bar. With Herng Tony Yao we also analyze the Left-Right Symmetric Model (LRSM)
