【 摘 要 】

The author presents three recent results from searches for exotic physics at the BABAR/PEP-II B-factory. These results span many of the samples produced at the B-factory, including B mesons, (tau) leptons, and (Upsilon)(3S) mesons. We have searched for CPT-violation in B(sup 0) mixing and find no significant deviation from the no-violation hypothesis. We have also searched for lepton-flavor-violating decays of the (tau) using (tau)(sup -) (yields) (omega)(ell)(sup -) and (tau)(sup -) (yields) (ell)(sup -)(ell)(sup +)(ell)(sup -) and their charge conjugates. We find no evidence for these processes and set upper limits on their branching fractions. Finally, we have searched for a low-mass Higgs boson in the decay (Upsilon)(3S) (yields) (gamma)A(sup 0), where the Higgs decays invisibly. We find no evidence for such a decay and set upper limits across a range of possible Higgs masses.
