Abstract: We simulate SU2 gauge theory with two massless Dirac fermions in theadjoint representation. We calculate the running of the Schroedinger Functionalcoupling and the renormalised quark mass over a wide range of length scales.The running of the coupling is consistent with the existence of an infraredfixed point IRFP, and we find 0.07 < gamma < 0.56 at the IRFP, depending onthe value of the critical coupling.
