本文对格点上伴随表象中具有一个狄拉克标量的SU（2）规范理论的研究作了一个重要的更新。特别地，我们考虑更大的体积，以及四个不同的规范耦合值。我们提供的光谱，包括胶子，费米子，和混合观测值，Polyakov回路，并从狄拉克模式数的费米子凝聚体的异常尺寸的结果。这些数据证实了该理论接近伴随费米子的共形窗口的下边界。我们的研究提供了重要的见解，实现不同的红外场景，已经为这个理论。
We present a major update on our investigations of SU(2) gauge theory with one Dirac flavor in the adjoint representation on the lattice. In particular we consider larger volumes, as well as four different values of the gauge coupling. We provide results for the spectrum including gluonic, fermionic, and hybrid observables, Polyakov loops, and the anomalous dimension of the fermionic condensate from the Dirac mode number. These data confirm that the theory is close to the lower boundary of the conformal window for adjoint fermions. Our investigations provide important insights regarding the realization of different infrared scenarios that have been conjectured for this theory.
