论文摘要
我们确定$θ$ - 角和轴轴物理学对$ SU（2）$ su（2）$ gauge理论的大电荷巴里恩领域的近形条动力学的影响。我们采用了一种有效的方法，该方法以理论中的拓扑用语增强了戈德斯通和dilaton的自由度。我们研究了不同的DILATON电位，包括建立系统计数方案的电位如何影响结果。通过状态操作员对应关系，我们将最低大电荷运算符的可能保形尺寸计算为$θ$项和DILATON电位的函数。
We determine the impact of the $θ$-angle and axion physics on the near conformal dynamics of the large-charge baryon sector of $SU(2)$ gauge theories with $N_f$ fermions in the fundamental representation. We employ an effective approach featuring Goldstone and dilaton degrees of freedom augmented by the topological terms in the theory. We investigate how different dilaton potentials, including the ones for which a systematic counting scheme can be established, affect the results. Via state-operator correspondence we compute the corrections to the would-be conformal dimensions of the lowest large-charge operators as a function of the $θ$ term and dilaton potential.
