Here, we report the study of B⁺→p¯ΛK⁺K^– and B+→¯pΛK⁺K⁺ decays using a 772 × 10⁶ B¯B pair data sample recorded on the Υ(4S) resonance with the Belle detector at KEKB. The following branching fractions are measured: B(B⁺ → p¯ΛK⁺K^–) = (4.10^+0.45_–0.43±0.50) × 10^–6, B(B⁺ → ¯pΛK⁺K⁺) = (3.70^+0.39_–0.37±0.44) × 10^–6, B(η_c → p¯ΛK^– + c.c.) = (2.83^+0.36_–0.34±0.35) × 10^–3 and B(B⁺ → p¯ΛΦ) = (7.95 ± 2.09 ± 0.77) × 10^–7, where c.c. denotes the corresponding charge-conjugation process. The intermediate resonance decays are excluded in the four-body decay measurements. We also find evidence for B(η_c → Λ(1520)¯Λ + c.c.) = (3.48 ± 1.48 ± 0.46) × 10^–3 and B(B⁺ → Λ(1520)¯ΛK⁺) = (2.23 ± 0.63 ± 0.25) × 10^–6. No significant signals are found for J/ψ → Λ(1520)¯Λ + c.c. and B⁺ → ¯Λ(1520)ΛK⁺; we set the 90% confidence level upper limits on their decay branching fractions as < 1.80 × 10^–3 and < 2.08 × 10^–6, respectively.
