Description

In a sample of 6.6x106 produced B mesons we have observed decays B→η'K , with branching fractions B(B+→η' K+)=(6.5+1.5-1.4 ±0.9)x10-5 and B(B0→η' K0)=(4.7+2.7-2.0 ±0.9)x10-5 . We have searched with comparable sensitivity for 17 related decays to final states containing an η or η' meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B→η'K signal. copyright 1998 The American Physical Society
