摘要：

The use of chirally rotated boundary conditions provides a formulation of the Schrodinger functional that is compatible with automatic O(a) improvement of Wilson fermions up to O(a) boundary contributions. The elimination of bulk O(a) 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. (C) 2012 Elsevier B.V. All rights reserved.
