在欧洲核子研究中心的大型强子对撞机上，ATLAS协作组正在寻找在8 TeV质心能量的质子-质子碰撞中产生的高度电离粒子。所用的数据集对应于的积分光度。一个定制的触发器大大提高了灵敏度，允许搜索这样的粒子与电荷和能量超出了以前的访问。没有事件被发现在信号区，导致生产截面上限在200-2500 GeV的范围内的磁单极子的磁荷，其中狄拉克电荷，并为稳定的粒子与电荷的范围内。模型相关的限制在给定的对生产的情况下，和模型无关的限制在粒子能量和伪快度的基准区域。
A search for highly ionizing particles produced in proton-proton collisions at 8 TeV center-of-mass energy is performed by the ATLAS Collaboration at the CERN Large Hadron Collider. The data set used corresponds to an integrated luminosity of. A customized trigger significantly increases the sensitivity, permitting a search for such particles with charges and energies beyond what was previously accessible. No events were found in the signal region, leading to production cross section upper limits in the mass range 200–2500 GeV for magnetic monopoles with magnetic charge in the range, whereis the Dirac charge, and for stable particles with electric charge in the range. Model-dependent limits are presented in given pair-production scenarios, and model-independent limits are presented in fiducial regions of particle energy and pseudorapidity.
