The Kaon B-parameter from Domain Wall Fermions

Presenter: Dave Antonio — University of Edinburgh

RBC and UKQCD collaborations

We present results from a calculation of BK on 2+1 flavour domain wall fermion lattices of spatial volume (2 fm)3 and lattice spacing a−1=1.62(4). We discuss in detail the systematic error estimates of our final, renormalised result.
