Quest for Exotically Charged Particles (Physics)

这一行动将为一名教师和一名研究生提供资金，以继续在现有的最高能量粒子碰撞中寻找奇异带电粒子。实验人员使用高灵敏度的可蚀刻固体径迹探测器来搜索狄拉克单极和其他高电离粒子--磁电荷也可以通过它在分光计漂移室磁场中的加速来识别。该项目包括继续进行现有的两次搜索：一次在特里斯坦(KEK，日本)，另一次在Tevatron的D-Zero地区(Fermilab)。LEP(欧洲核子研究中心)与Opal合作的一项新搜索是其他搜索的延伸，因为它发生在可用的最高e+e湮灭能量下。尽管目前关于大统一的理论预测磁单极子质量远远高于任何加速器可以达到的质量，但只要加速器能量更高，可以设定更好的限制，这样的搜索仍然应该作为实验检查进行。

This action will provide funds for one faculty and one graduate student to continue a search for exotically charged particles in the highest energy particle collisions available. The experimenters use highly sensitive etchable solid state track detectors for the search of Dirac monopoles and other highly ionizing particles--magnetic charge may also be identified by its acceleration in the magnetic field of a spectrometer drift chamber. The project includes the continuation of two existing searches: one at TRISTAN (KEK Japan) and the other at the D- Zero area of the Tevatron (Fermilab). One new search at LEP (CERN) in collaboration with OPAL is an extension of the others in that it is occurring at the highest e+e- annihilations energy available. Although current theories on grand unification predict magnetic monopole masses well above any accessible at accelerators, such a search should still be carried out as experimental checks whenever better limits can be set at higher accelerator energies.
