Query: Lattice artefacts in the Schr\"odinger Functional coupling for strongly
  interacting theories   Models of Dynamical Electroweak Symmetry Breaking are expected to display a
quasi-conformal scaling behaviour in order to accommodate experimental
constraints. The scaling properties of a theory can be studied using finite
volume renormalisation schemes. Among these, the most practical ones are based
on the Schr\"odinger Functional (SF). However, lattices accessible in nu-
merical simulations suffer from potentially large cutoff effects and special
care has to be taken to remove these effects. Here we will study the standard
setup of the SF with Wilson quarks and a setup with chirally rotated boundary
conditions. We study the step scaling function for SU(2) and SU(3) gauge groups
in the fundamental, 2-index symmetric and adjoint representations. We per- form
the O(a)-improvement of both setups to 1-loop order in perturbation theory, and
we describe a way of minimising higher order cutoff effects by a redefinition
of the renormalised coupling.
