最小步行技术中的有限尺寸标度

Finite size scaling in minimal walking technicolor

Joel Giedt, Evan Weinberg

摘要:

我们将观测量与SU(2)格点规范理论中的有限尺寸标度假设进行了比较。我们得到的拟合产生的异常质量尺寸的估计是一致的四个环路微扰理论:$γ= 0.51 \pm 0.16$,由于系统的不确定性在有限尺寸标度分析的错误。结果略大于一个薛定谔函数研究(由1.3 $σ$),但与另一个一致。

英文摘要:

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: $γ= 0.51 \pm 0.16$, with the error due to systematic uncertainties in the finite size scaling analysis. The result is somewhat larger than one Schrödinger functional study (by 1.3$σ$) but consistent with another.
