Weinberg-Salam模型中的振荡反偶对

Oscillating monopole-antimonopole pair in the Weinberg-Salam model

Dan Zhu, Khai-Ming Wong, Guo-Quan Wong

摘要:

我们进一步研究了标准Weinberg-Salam理论中轴对称的反对称对的性质。这些数值解的行为与SU(2)Yang-Mills-Higgs理论中的对应物完全不同,因为极点现在被通量弦束缚。我们的结果证实,这些解决方案的能量驻留在13.17 - 21.02 TeV的范围内。此外,我们发现了强有力的证据表明,这种配置是时间依赖性的,并发现了一个能量振荡现象之间的反和反的反,这是与对称性的解决方案。最后,我们数值计算的解决方案,并确认其值确实是$\frac{4π}{e}\sin^2θ_{\scalebox{.5} {W}}$,预测Y。70年代的南部。与直觉相反的是,磁荷是沿着弦展开和分布的,而不是集中在磁极附近。

英文摘要:

We investigate further the properties of axially symmetrical monopole-antimonopole pair in the standard Weinberg-Salam theory. These numerical solutions behave quite differently from their counterparts in the SU(2) Yang-Mills-Higgs theory as the poles are now bounded by a flux string. Our results confirm that the energy of these solutions resides in a range of 13.17 - 21.02 TeV. In addition, we found strong evidence suggesting this configuration is time-dependent and discovered an energy oscillation phenomenon between the monopole and anti-monopole, which is associated with the symmetry of the solution. Finally, we calculate numerically the magnetic charge of the solution and confirm that its value is indeed $\frac{4π}{e}\sin^2θ_{\scalebox{.5} {W}}$, as predicted by Y. Nambu in the 1970s. Counterintuitively, the magnetic charge is spread out and distributed along the string instead of concentrated near the poles.
