2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/125895We present measurements from Belle and BABAR of the time-dependent CP-violation parameters S and C in B->eta'K0 decays. Both experiments observe mixing-induced CP violation with a significance of more than 5 standard deviations in this b-> s penguin dominated mode. We also compare with theoretical expectations and discuss the latest results for SU(3)-related decays which are useful for obtaining bounds on the expected values of S and C.4 pages, 4 figures, sumitted to "4th International Workshop on the CKM Unitarity Triangle, Nagoya, Japan, 2006"High Energy Physics - Experimenttext
