标题： On Magneticons and some related matters

摘要： 本文中，“magneticon”这一名称指的是通过将经典电磁学的一种对称性——称为二重性对称性——纳入点状费米子结构的某种模型而预测出的磁荷自旋1/2粒子。 （实际上，预计会出现一个完整的谱系，包括强子和轻子类的这类磁荷粒子。） 这些magneticon中最轻的是轻子性质的，并且预计其电磁荷的大小（以高斯单位）与电子相同，只是它是磁性的。 伴随着这种磁性费米子的谱系，建议可能还存在第二种光子，或称为磁光子。 在简要介绍之后，使用由经典电磁学的双势拉格朗日形式提出的最低阶量子微扰近似方法，通过时空代数的使用来包含磁荷和电流，推导出电子-正电子湮灭产生magneticon的对产生截面。 讨论了如何将这些想法纳入涉及磁荷和磁光子的其他量子相互作用中。 这些相互作用包括电子-magneticon散射和magneticon真空极化环。 探讨了过去和未来实验中观察这些磁性粒子的可能性，并作出了一些预测。 显示英文摘要

摘要： The name "magneticon" in this paper refers to a magnetically charged spin 1/2 particle predicted by incorporating a symmetry of classical electromagnetism, called dyality symmetry, into a certain model for the structure of point-like fermions. (Actually, it is anticipated that there would be a full spectrum, both hadronic and leptonic, of such magnetically charged particles.) The lightest of these magneticons is anticipated to be leptonic in nature and predicted to have the same magnitude of electromagnetic charge (in Gaussian units) as the electron, except that it is magnetic. Accompanying this spectrum of magnetic fermions, it is suggested that there may also be a second, or magnetic, photon. After a brief introduction, the pair production cross section of magneticons by electron-positron annihilation is derived using a lowest order quantum perturbation approximation suggested by a two-potential Lagrangian form for classical electromagnetism, symmetrized through the use of space-time algebra to include magnetic charge and currents. A discussion of how these ideas might be included in other quantum interactions involving magnetic charges and the magnetic photon is undertaken. These interactions include electron-magneticon scattering and magneticon vacuum polarization loops. Possibilities for the observation of these magnetic particles in past experiments, as well as future experiments, are explored, and some predictions are made.
