| 英文摘要 | We describe searches for decays to two-body charmless final states eta(')eta, eta(')pi(0) and eta pi(0) of b-0 mesons produced in e(+)e(-) annihilation. the data, collected with the babar detector at the stanford linear accelerator center, represent 232x10(6) produced b (b) over bar pairs. the results for branching fractions are, in units of 10(-6) (upper limits at 90% c.l.): b(b-0->eta(')eta)=0.2(-0.5)(+0.7)+/- 0.4(< 1.7), b(b-0->eta pi(0))=0.6(-0.4)(+0.5)+/- 0.1(< 1.3), and b(b-0->eta(')pi(0))=0.8(-0.6)(+0.8)+/- 0.1(< 2.1). the first error quoted is statistical and the second systematic. |
