Title: Measurements of branching fraction and direct C P asymmetry in B ± K S 0 K S 0 K ± and a search for B ± K S 0 K S 0 π ±

Abstract

We study charmless hadronic decays of charged $B$ mesons to the final states $${K}_{S}^{0}{K}_{S}^{0}{K}^{\pm{}}$$ and $${K}_{S}^{0}{K}_{S}^{0}{{\pi}}^{\pm{}}$$ using a $$711\text{ }\text{ }{\mathrm{fb}}^{{-}1}$$ data sample that contains $$772\times{}{10}^{6}$$ $$B\overline{B}$$ pairs and was collected at the $$\mathrm{{\Upsilon}}(4S)$$ resonance with the Belle detector at the KEKB asymmetric-energy $${e}^{+}{e}^{{-}}$$ collider. For $${B}^{\pm{}}{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}{K}^{\pm{}}$$, the measured branching fraction and direct $CP$ asymmetry are $$[10.42\pm{}0.43(\mathrm{stat})\pm{}0.22(\mathrm{syst})]\times{}{10}^{{-}6}$$ and $$[+1.6\pm{}3.9(\mathrm{stat})\pm{}0.9(\mathrm{syst})]$$%, respectively. In the absence of a statistically significant signal for $${B}^{\pm{}}{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}{{\pi}}^{\pm{}}$$, we obtain a 90% confidence-level upper limit on its branching fraction as $$8.7\times{}{10}^{{-}7}$$.
