| Abstract: | We present the first results for the K(sub)l3 form factor from simulations with 2+1 flavors of dynamical domain wall quarks. Combining our result, namely, f₊(0)=0.964(5) with the latest experimental results for K(sub)l3 decays leads to |V(sub)us|=0.2249(14), reducing the uncertaintity in this important parameter. For the O(p⁶) term in the chiral expansion we obtain Δf=-0.013(5). |
