Abstract
We present the first results for neutral kaon mixing using 2+1 flavors of domain wall fermions. A new approach is used to extrapolate to the physical up and down quark masses from our numerical studies with pion masses in the range 240 -- 420 MeV; only chiral symmetry is assumed and the kaon is not assumed to be light. Our main result is where the first error is statistical and the second incorporates estimates for all systematic errors.
