Abstract

We report measurements and searches for resonant B± → K± h → K± γ γ decays where h is a η, η, ηc, ηc (2 S), χc 0, χc 2, J / ψ meson or the X (3872) particle. The results are based on a data sample containing 535 million B over(B, ̄) pairs collected with the Belle detector at the KEKB e+ e- asymmetric-energy collider operating at the Υ{hooked} (4 S) resonance. Signals are observed in the modes with η and η, and we obtain evidence for a signal in the mode with ηc. We measure B (B± → K± η → K± γ γ) = (0.87-0.15 +0.16 (stat)-0.07 +0.10 (syst)) × 10-6, B (B± → K± η → K± γ γ) = (1.40-0.15 +0.16 (stat)-0.12 +0.15 (syst)) × 10-6 and B (B± → K± ηc → K± γ γ) = (0.22-0.07 +0.09 (stat)-0.02 +0.04 (syst)) × 10-6. We set upper limits on the branching fractions of the other modes.
