Query: Measurements of |Vus| and Searches for Violation of Lepton Universality
  and CPT in Tau Decays at BaBar   Using data collected with the BaBar detector at PEP-II at SLAC, we report on
several tau lepton measurements that are used to determine the modulus of the
Cabibbo-Kobayashi-Maskawa matrix element Vus, and to check the Standard Model
predictions of lepton universality and CPT conservation.
