Abstract
We present the latest results from the UKQCD/RBC collaborations for the Kl3 form factor with 2 + 1 flavours of dynamical domain wall quarks. Simulations are performed on 163 × 32 × 16 and 243 × 64 × 16 lattices with three values of the light quark mass, allowing for an extrapolation to the chiral limit. After interpolating to zero momentum transfer, we obtain the preliminary result f+ Kπ (0) = 0.9609(51) (or Δf = -0.0161(51)), which is in agreement with the result of Leutwyler & Roos.
