Abstract

We 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 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) = 0.9680(16), which is in excellent agreement with an earlier N_f = 2 result.
