Precision computation of B_K in quenched lattice QCD
P. Dimopoulos, J. Heitger, C. Pena +2
We present the results of a precision computation of B_K with Wilson fermions. Simulations are performed at different lattice spacings, enabling continuum limit extrapolations. Two…

NLO anomalous dimension of multiplicatively renormalizable four-fermion operators in Schroedinger Functional schemes
Filippo Palombi, Carlos Pena, Stefan Sint
Renormalization constants for multiplicatively renormalizable parity-odd four-fermion operators are computed in various different Schroedinger Functional (SF) schemes and lattice r…

Some remarks on O(a) improved twisted mass QCD
Roberto Frezzotti, Stefan Sint
Twisted mass QCD (tmQCD) has been introduced as a solution to the problem of unphysical fermion zero modes in lattice QCD with quarks of the Wilson type. We here argue that O(a) im…
