We note that B(D-0 -> omega eta) is measured for the first time and that B(D-0 -> eta eta) is measured with much improved precision.eninfo:eu-repo/semantics/openAccessMeasurements of the branching fractions of the singly Cabibbo-suppressed decays D-0 -> omega eta, eta(()'())pi(0) and eta(()'())etaArticle2-s2.0-8504485342510.1103/PhysRevD.97.052005Q1WOS:000427603400002
