Evidence for the Rare Decay, B--> J/psi eta K
We report evidence for the B meson decays, B{sup {+-}} {yields} J/{psi}{eta}K{sup {+-}} and B{sup 0} {yields} J/{psi}{eta}K{sub S}{sup 0}, using 90 million B{bar B} events collected at the {Upsilon}(4S) resonance with the BABAR detector at the PEP-II e{sup +}e{sup -} asymmetric-energy storage ring. We obtain preliminary branching fractions in the charged and neutral channels of (10.8 {+-} 2.3(stat.) {+-} 2.4(syst.)) x 10{sup -5} and (8.4 {+-} 2.6(stat.) {+-} 2.7(syst.)) x 10{sup -5}, respectively.
