Search for $B^+ \to K_S K_S h^+$ decays at Belle

We present updated measurements of charmless decays of charged B mesons to the three-body final states of $K_S K_S K^+$ and $K_S K_S \pi^+$, based on a data sample containing $770 \times 10^6$ $B\bar{B}$ events. The data were recorded with the Belle detector operating near the $\Upsilon(4S)$ resonance at the KEKB asymmetric-energy $e^+ e^-$ collider. The $B^+ \to K_S K_S K^+$ and $B^+ \to K_S K_S \pi^+$ decays proceed via the $b \to s$ and $b \to d$ flavor-changing neutral current (FCNC) transitions, respectively, providing a good probe for new physics beyond the standard model (SM). We report the results on the branching fractions and direct CP asymmetries for both the decay channels.
