Dalitz Plot Analysis of $B^+ \to h^+h^-h^+$

We present preliminary results of a maximum-likelihood Dalitz-plot analysis of the charmless hadronic $B^{\pm}$ decays to the final states $\pi^{\pm}\pi^{\mp}\pi^{\pm}$, $K^{\pm}\pi^{\mp}\pi^{\pm}$, and $K^{\pm}K^{\mp}K^{\pm}$ from data corresponding to an integrated on-resonance luminosity of 211 $\rm fb^{-1}$ recorded by the BaBar experiment at the SLAC PEP-II asymmetric-energy $B$ Factory. We measure the total branching fractions and asymmetries and provide fit fractions, fit fraction asymmetries and phases for the intermediate resonance states.
