This work presents measurements of the branching fractions for tau decays to 3-prong final states using a data set of 430 million tau lepton pairs, corresponding to an integrated luminosity of $468 fb^-1, collected with the BaBar detector at the PEP-II asymmetric energy e^+e^- storage rings. The tau^- -> 3pi^- eta nu_tau, tau^- ->pi^- 2pi^0 omega nu_tau and tau^- -> f_1(1285) pi^- nu_tau branching fractions are presented as well as a measurement of the non-resonant component of the tau^- -> 3pi^- 3pi^0 nu_tau decay. In addition this work sets a new limit on the branching fraction of the isospin-forbidden, second-class current decay tau^- -> pi^- eta'(958) nu_tau. / Graduate
