1201.6262 (Joel Giedt et al.)

Finite size scaling in minimal walking technicolor    [PDF]

Joel Giedt, Evan Weinberg
We compare observables to the finite size scaling hypothesis in SU(2) lattice
gauge theory with two Dirac fermions in the adjoint representation. The fits
that we obtain yield an estimate of the anomalous mass dimension that is
consistent with four loop perturbation theory: $\gamma = 0.51 \pm 0.16$, with
the error due to systematic uncertainties in the finite size scaling analysis.
The result is somewhat larger than one Schr\"odinger functional study (by
1.3$\sigma$) but consistent with another.
