在SU（2）规范理论的格点形式中，我们用Schroedinger泛函方法测量了耦合常数的演化.我们观察到强有力的证据，红外固定点，理论成为共形。我们测量的{beta}函数和耦合常数作为能量sca 0008的函数。
We measure the evolution of the coupling constant using the Schroedinger functional method in the lattice formulation of SU(2) gauge theory with two massless Dirac fermions in the adjoint representation. We observe strong evidence for an infrared fixed point, where the theory becomes conformal. We measure the {beta} function and the coupling constant as a function of the energy sca0008.
