Abstract
We study charmless hadronic decays of charged B mesons to the final states (KSKSK +/-)-K-0-K-0 and (KSKS0)-K-0 pi(+/-) using a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs and was collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) ethorne-collider. For B-+/- -> (KSKSK +/-)-K-0-K-0, the measured branching fraction and direct CP asymmetry are [10.42 +/- 0.43(stat) +/- 0.22(syst)] x 10(-6) and [+1.6 +/- 3.9(stat) +/- 0.9(syst)] %, respectively. In the absence of a statistically significant signal for B-+/- -> (KSKS0)-K-0 pi(+/-), we obtain a 90% confidence-level upper limit on its branching fraction as 8.7 x 10(-7).
