dc.descriptionWe present the latest results from the UKQCD/RBC collaborations for the K_l3 form factor with 2+1 flavours of dynamical domain wall quarks. Simulations are performed on 16^3x32x16 and 24^3x64x16 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.
