论文摘要
我们探索了标准模型(SM)的测量重子数对称扩展中轴承的有效理论,其中轴是从Dine-Fischler-Srednicki-Zhitnitsky(DFSZ)模型构建中实现的。整合异构体会意识到有效的威尔逊系数的模式,反映了异常的peccei-quinn和测量的baryon数字对称性之间的分解。我们构建和分析了轴突有效理论的手性转化不变性,以考虑可能的风味抗化轴承耦合。我们计算并研究了轴轴和$ z'u $ boson的独特现象学,并在$ \ {m_ {z'}中介绍了这些粒子的当前碰撞器限制,g_b \} $,$ \ {m_a,g_ {m_a,g_ {g_ {aγγ}} $,and $ \ planEs and $ \ \ _a^$}
We explore the effective theory of an axion in a gauged baryon number symmetry extension of the Standard Model (SM), where the axion is realized from a Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) model construction. Integrating out the anomalons realizes a pattern of effective Wilson coefficients reflecting the factorization between the anomalous Peccei-Quinn and gauged baryon number symmetries. We construct and analyze the chiral transformation invariance of the axion effective theory, accounting for possible flavor-violating axion couplings. We calculate and study the unique phenomenology of the axion and $Z'$ boson, and we present the current collider limits on these particles in the $\{m_{Z'}, g_B\}$, $\{m_a, G_{a γγ} \}$, and $\{m_a, f_a^{-1}\}$ planes.
