# Measurement of CP-Violating Asymmetries in B0 to (rho pi)0 using a Time-Dependent Dalitz Plot Analysis

## Abstract

We report a measurement of CP-violating asymmetries in B{sup 0} {yields} ({rho}{pi}){sup 0} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} decays using a time-dependent Dalitz plot analysis. The results are obtained from a data sample of 375 million {Upsilon}(4S) {yields} B{bar B} decays, collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure 26 coefficients of the bilinear form-factor terms occurring in the time-dependent decay rate of the B{sup 0} meson. We derive the physically relevant quantities from these coefficients. In particular, we measure a constraint on the angle {alpha} of the Unitarity Triangle.
