摘要

轻子的磁矩是一个有趣的量,它对标准模型之外的物理有潜在的敏感性。电弱规范不变性意味着对它的重大新物理贡献是以涉及希格斯玻色子的算子的形式出现的,这意味着罕见的希格斯衰变能够探测到与$a_\tau$相同的物理。我们研究了未来高能轻子(电子或介子)对撞机中罕见希格斯衰变的前景,并发现这样一个收集几个ab$^{-1}$的项目将能够将我们对这种物理的理解提高大约10倍,与高亮度LHC的预期范围相比。

The $\tau$ Magnetic Dipole Moment at Future Lepton Colliders
The magnetic moment of the $\tau$ lepton is an interesting quantity that is potentially sensitive to physics beyond the Standard Model. Electroweak gauge invariance implies that a heavy new physics contribution to it takes the form of an operator which involves the Higgs boson, implying that rare Higgs decays are able to probe the same physics as $a_\tau$. We examine the prospects for rare Higgs decays at future high energy lepton (electron or muon) colliders, and find that such a project collecting a few ab$^{-1}$ would be able to advance our understanding of this physics by roughly a factor of 10 compared to the expected reach of the high luminosity LHC.
