本文研究标准模型味对称性在磁单极存在下的命运,发现电弱反常会在单极-费米子散射中诱导重子数与轻子数变化,并在Pati-Salam和三统一理论中验证该机制。
AI 中文摘要
我们研究了与标准模型味相关的广义对称性及其在存在磁单极时的命运。这揭示了一个显著的现象学后果:即使重子数和轻子数在经典上守恒,电弱反常也会在任意激活该反常的磁单极-费米子散射中诱导$\u0394B = \u0394L \u2208 3\u2124$。我们在Pati-Salam理论和三统一理论中演示了这一机制。
英文摘要
We study the generalized symmetries associated with Standard Model flavor and their fate in the presence of magnetic monopoles. This illuminates a striking phenomenological consequence: even when baryon and lepton number are classically conserved, the electroweak anomaly induces $ΔB = ΔL \in 3 \mathbb{Z}$ in monopole-fermion scattering for any monopole activating the anomaly. We demonstrate this mechanism in Pati-Salam theory and trinification.
