Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishWe present measurements of the branching fractions for B0-meson decays to η′K0 and ωK0, and of the branching fractions and CP-violation charge asymmetries for B+-meson decays to ηπ+, ηK+, η′π+, η′K+, ωπ+, and ωK+. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 383×10^6 BB̅ pairs produced in e+e- annihilation. The measurements agree with previous results; we find no evidence for direct CP violation.
