Chirally rotated Schroedinger functional: non-perturbative tuning in the quenched approximation
Abstract
The use of chirally rotated boundary conditions provides a formulation of the Schroedinger functional that is compatible with automatic O(a)-improvement of Wilson fermions in the bulk. The elimination of bulk O(a) terms requires the non-perturbative tuning of the critical mass and one additional boundary counterterm. We present the results of such a tuning in the quenched approximation at three values of the renormalised gauge coupling and for a range of lattice spacings.
