论文摘要
我们提出了第一个对应于SU（2）$ \ times $ u（1）Weinberg-Salam（WS）理论中的Cho-Maison Monopole和抗巨焦（MAP）的第一个数值解。单孔有限分开，而每个杆携带磁性电荷$ \ pm4π/e $。正极位于上半球，而负极位于下半球。调查了Cho-Maison地图的一系列Weinberg角度，$ 0.4675 \ leq \tanθ_w\ leq10 $，以及Higgs自耦合，$ 0 \leqβ\leqβ\ leq1.7704 $。计算和分析了数值解的磁偶极矩（$μ_m$）和极点分离（$ d_z $）。然而，由于单孔位置的点奇异性，系统的总能量是无限的。
We present the first numerical solution that corresponds to a pair of Cho-Maison monopole and antimonopole (MAP) in the SU(2)$\times$U(1) Weinberg-Salam (WS) theory. The monopoles are finitely separated, while each pole carries magnetic charge $\pm 4π/e$. The positive pole is situated in the upper hemisphere, whereas the negative pole is in the lower hemisphere. The Cho-Maison MAP was investigated for a range of Weinberg angle, $0.4675\leq\tanθ_W\leq10$, and Higgs self-coupling, $0\leqβ\leq1.7704$. Magnetic dipole moment ($μ_m$) and pole separation ($d_z$) of the numerical solutions are calculated and analyzed. Total energy of the system, however, is infinite due to point singularities at the locations of monopoles.
