Abstract
We describe searches for decays of B mesons to the charmless final states eta(')eta K-'. The data consist of 228x10(6) B ($) over barB pairs produced in e(+)e(-) annihilation, collected with the BABAR detector at the Stanford Linear Accelerator Center. The 90% confidence level upper limits for the branching fractions are B(B-0 ->eta(')eta K-'(0))< 31x10(-6) and B(B+->eta(')eta K-'(+))< 25x10(-6).File in questo prodotto:
