A dynamical study of the chirally rotated Schr\"odinger functional in QCD

Understand

The chirally rotated Schr\"odinger functional for Wilson-fermions allows for finite-volume, mass-independent renormalization schemes compatible with automatic O($a$) improvement.

• So far, in QCD, the set-up has only been studied in the quenched approximation.
• Here we present first results for $N_{\rm f} = 2$ dynamical quark-flavours for several renormalization factors of quark-bilinears.
• We discuss how these renormalization factors can be easily obtained from simple ratios of two-point functions, and show how automatic O($a$) improvement is at work.
