2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/168072We report an updated amplitude analysis of the charmless hadronic decays of neutral B mesons to K+pi-pi0. With a sample of 454 million Upsilon(4S) -> B0B0bar decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B0 and B0bar decays and determine the corresponding CP-averaged fit fractions and charge asymmetries.24 pages, 10 postscript figures, submitted to ICHEP2008High Energy Physics - Experimenttext
