标题： On Asymptotic safety in 4D gauge theory with additional dimension=4 operators

摘要： 我们研究了四维$SU(N_c)$量子场论中的相互作用不动点，该理论耦合了$N_f$种颜色费米子和$N_f^2$个无色标量。在Veneziano极限下，利用所有可能的四次标量算符的丰富结构，我们发现了一个具有稳定真空和中间交叉区域的相互作用共形不动点。我们在规范耦合的四级微扰和Yukawa耦合及标量耦合的三级微扰下进行了计算。我们还考虑了场、标量质量平方以及一类三维算符的反常维度。 显示英文摘要

摘要： We study interacting fixed points of simple quantum field theory in four-dimensional $SU(N_c)$ coupled to $N_f$ species of color fermions and $N_f^2$ colorless scalars in the Veneziano limit. Using the rich structure of all possible quartic scalar operators, we find an interacting conformal fixed point with stable vacua and crossovers inbetween. We perform calculations in perturbation theory up to four loop in the gauge and three loop in the Yukawa and scalar couplings. We also consider anomalous dimensions for fields, scalar mass squared, and a class of dimension-three operators.
