We report measurements and searches for resonant B±→K±h→K±γγ decays where h is a η, η′, ηc, ηc(2S), χc0, χc2, J/ψ meson or the X(3872) particle. The results are based on a data sample containing 535 million BB¯ pairs collected with the Belle detector at the KEKB e+e− asymmetric-energy collider operating at the ϒ(4S) resonance. Signals are observed in the modes with η and η′, and we obtain evidence...
