Description
Quantum Chromodynamics with two mass degenerate light quark flavors and an additional single heavier quark flavor has been simulated on the lattice using the domain wall fermion formulation. These simulations cover a range of dynamical pion masses between 300 and 420 MeV and were performed at two different values for the lattice spacing with 1/a=1.73 and 2.32 GeV and a linear lattice extent of 2.8 fm. This talk will focus on the determination of the kaon bag parameter B_K and the semi-leptonic kaon form factor K_l3. The various methods for extrapolating these quantities to the limit of physical light quark mass will be evaluated.
