Search for B+ to X(3872) K+, X(3872) to J/psi gamma
In a study of B{sup +} {yields} J/{psi}{gamma}K{sup +} decays, they find evidence for the radiative decay X(3872) {yields} J/{psi}{gamma} with a statistical significance of 3.4{sigma}. They measure the product of branching fractions {Beta}(B{sup +} {yields} X(3872)K{sup +}) {center_dot} {Beta}(X(3872) {yields} J/{psi}{gamma}) = (3.3 {+-} 1.0 {+-} 0.3) x 10{sup -6}, where the uncertainties are statistical and systematic, respectively. They also measure the branching fraction {Beta}(B{sup +} {yields} {chi}{sub c1}K{sup +}) = (4.9 {+-} 0.20 {+-} 0.4) x 10{sup -4}. These results are obtained from (287 {+-} 3) million B{bar B} decays collected at the {Upsilon}(4S) resonance with the BABAR detector at the PEP-II B Factory at SLAC.
