$K^{0}-\overline{K}^{0}$ mixing from the Schroedinger functional and twisted mass QCD
We describe how the Schroedinger functional and twisted mass QCD can be used to compute the kaon B-parameter B_K on the lattice with Wilson fermions. This new approach is expected to reduce the systematic uncertainties on B_K through a better control of its (nonperturbative) renormalisation. Prelimi...
