Magnetic monopoles, if they exist, would be produced amply in strong magnetic fields and high temperatures via the thermal Schwinger process. Such circumstances arise in heavy-ion collisions and in neutron stars, both of which imply lower bounds on the mass of possible magnetic monopoles. In showing this, we construct the cross section for pair production of magnetic monopoles in heavy-ion collisions, which indicates that they are particularly promising for experimental searches such as MoEDAL.
磁单极子若存在，将在强磁场和高温下通过热施温格过程大量产生。这种情况出现在重离子碰撞和中子星中，这两者都暗示了可能存在的磁单极子质量的下限。在证明这一点的过程中，我们构建了重离子碰撞中磁单极子对产生的截面，这表明它们对于像MoEDAL这样的实验搜索特别有前景。
