AMPLITUDE ANALYSIS OF B{sup +-} --> {pi}{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}} and B{sup {+-}} --> K{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}}
The authors present preliminary results of a maximum-likelihood Dalitz-plot analysis of the charmless hadronic B{sup {+-}} decays to the final states {pi}{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}} and K{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}} from data corresponding to an integrated on-resonance luminosity of 166 fb{sup -1} recorded by the BABAR experiment at the SLAC PEP-II asymmetric-energy B Factory. They measure the total branching fractions B(B{sup {+-}} --> {pi}{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}}) = (16.2 {+-} 2.1 {+-} 1.3) x 10{sup -6} and B(B{sup {+-}} --> K{sup {+-}}{pi}{sup {-+}}{pi}{sup {+-}}) = (61.4 {+-} 2.4 {+-} 4.5) x 10{sup -6}, and provide fit fractions and phases for intermediate resonance states.
