We study the decays of B→K (*) ℓ + ℓ - in split supersymmetry with R-parity violation. We find that the decay branching ratio of B→Kτ + τ - in the new physics model due to the scalar interactions can be 1.8×10 -6 which is about one order of magnitude larger than in the standard model, whereas those of B→Kℓ + ℓ - (ℓ=e and μ) and the K* modes are insensitive to the new physics. On the other hand, the forward–backward asymmetries of B→Kτ + τ - and Kμ + μ - , vanishing in the standard model, can be over 10 and 1%, respectively. In addition, we show that the new interactions will significantly change the forward–backward asymmetry in B→K*τ + τ - .
