论文摘要
在这项工作中,我们通过利用基于两体和四体相互作用的零件的有效田间理论来研究自旋零和自旋的单极管之间的相互作用。特别是,我们分析了单极抗抗斜杆(即垄断)的结合状态的形成。与通常的电荷共轭相比,研究了磁性电荷共轭对称性,以定义粒子基础,为此,我们找到具有相对较小的结合能的结合状态溶液,这使我们能够识别有效的Lagrangians中参数的边界。在特定的重新归一化方案中,对其质量,结合能和散射长度的估计作为单极质量和相互作用强度进行。我们还检查了该方法的一般有效性以及检测蒙托的可行性。
In this work we investigate the interaction between spin-zero and spin-one monopoles by making use of an effective field theory based on two-body and four-body interaction parts. In particular, we analyze the formation of bound state of monopole-antimonopole (i.e. monopolium). The magnetic-charge conjugation symmetry is studied in analogy to the usual charge conjugation to define a particle basis, for which we find bound-state solutions with relatively small binding energies and which allows us to identify the bounds on the parameters in the effective Lagrangians. Estimations of their masses, binding energies and scattering lengths are performed as functions of monopole masses and interaction strength in a specific renormalization scheme. We also examine the general validity of the approach and the feasibility of detecting the monopolium.
