A quenched study of the Schrödinger functional with chirally rotated boundary conditions: Non-perturbative tuning Original Research Article

The use of chirally rotated boundary conditions provides a formulation of the Schrödinger functional that is compatible with automatic image improvement of Wilson fermions up to image boundary contributions. The elimination of bulk image effects requires the non-perturbative tuning of the critical mass and one additional boundary counterterm. We present the results of such a tuning in a quenched setup for several values of the renormalized gauge coupling, from perturbative to non-perturbative regimes, and for a range of lattice spacings. We also check that the correct boundary conditions and symmetries are restored in the continuum limit.
