Implications of Non-Standard CP Violation in Hadronic $B$-Decays

Abstract

We investigate a class of models for new physics which could produce a large difference in sin 2 beta between B0-> J/ψK(S) and the ``pure penguin'' mode B0-> phi K(S). In such models, the dominant effect is through a Z-penguin and therefore a pattern of deviation in sin 2beta as measured in B0-> chi(1) K(S); eta(c) K(S); J/ψK(S) and psi-prime K(S) is predicted. If the preliminary data concerning the discrepancy between J/ψK(S) and phi K(S) proves correct in magnitude, discrepancies in these other modes would likely be observable. We also consider the effects such new physics could have on the B(s) system and the isospin analysis of B-> Kπ. We compare this scenario with a scenario where contributions to sin 2beta in various modes is produced by gluino loops and down squark mixing.
