Magnetic monopoles, particles with magnetic charge, are among the most interesting hypothetical elementary particles that are being searched for with the Large Hadron Collider (LHC) at CERN, where the MoEDAL experiment has been specifically designed for this purpose. No direct evidence of them has been found in indirect or direct searches so far, but there are strong theoretical reasons to believe that they exist, and their mass could be low enough to allow them to be produced at the LHC. However, there is currently no useful quantum field theory description of magnetic monopoles, and therefore there are no theoretical predictions of their production cross section. The aim of this project is to develop and use lattice field theory simulations and other non-perturbative techniques to carry out this computation. The student will become a member of the MoEDAL collaboration, and the results will be used in the analysis of the data from the experiment.

磁单极子，带有磁荷的粒子，是欧洲核子研究中心大型强子对撞机（LHC）正在寻找的最有趣的假设基本粒子之一，MoEDAL实验就是为此目的而专门设计的。到目前为止，在间接或直接搜索中还没有发现它们的直接证据，但有强有力的理论理由相信它们存在，并且它们的质量可能足够低，可以在LHC中产生。然而，目前没有有用的量子场论描述磁单极子，因此没有理论预测其生产截面。该项目的目的是开发和使用格场理论模拟和其他非微扰技术来进行这种计算。学生将成为MoEDAL合作的成员，其结果将用于分析实验数据。
