2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/37809We present preliminary improved measurements of the branching fractions of the color-suppressed decays B0bar -> D0 h0, where h0 represents the three light neutral mesons pi0, eta and omega. The measurements are based on a data sample of 140fb-1 collected at the Upsilon(4S) with the Belle detector at the KEKB energy-asymmetric e+e- collider, corresponding to seven times the luminosity of the previous Belle measurements.14 pages, 5 figures, submitted to ICHEP2004, Beijing, ChinaHigh Energy Physics - Experimenttext
