μ子异常磁矩()的长期差异暗示了超越粒子物理标准模型的新物理学。在本文中,我们证明了新的重大物理贡献可以在质心能量高达2的μ子对撞机上充分测试。即使在这个能量范围内没有新的粒子,人们也可以通过通往希格斯玻色子和单色光子的通道直接测量算子。特别是后一种方法,如果未来建造的探测器的效率接近完美,则可以在20 b[5]能级的月球对撞机上以集成光度进行测试,这是最具挑战性的情况。
The long-standing discrepancy of the muon anomalous magnetic moment () is a hint of new physics beyond the standard model of particle physics. In this paper, we show that heavy new physics contribution can be fully tested at a muon collider with a center-of-mass energy up towith. Even if there is no new particle in this energy range, one can measure theoperator directly via the channel to a Higgs boson and a monochromatic photon. In particular, the latter process, which is the most challenging case, can be tested in themuon collider at the 2 [5]level withbeing the integrated luminosity if the efficiency of the detector built in the future is almost perfect.
