AI 中文摘要
10 TeV缪子对撞机通过其较大的矢量玻色子融合产生率,为希格斯扇区的精密研究提供了强大的环境。本综述介绍了对单希格斯和双希格斯产生截面、希格斯玻色子质量以及三线性希格斯自耦合的预期灵敏度。这些预期结果基于对MUSIC探测器的详细模拟,包括机器诱导背景,针对两个实验的基线配置,每个实验收集10 $\mathrm{ab}^{-1}$的积分亮度。$H\to b\bar{b}$和$H\to WW^\ast$产生截面可分别以0.18%和0.35%的统计精度测量,而$H\to\gamma\gamma$、$H\to ZZ^\ast$和$H\to\mu^+\mu^-$的预期精度分别为2.6%、4.2%和6.9%。结合$H\to b\bar{b}$、$H\to\gamma\gamma$和$H\to\mu^+\mu^-$通道,预期希格斯玻色子质量精度约为19 MeV。双希格斯产生可在$HH\to b\bar{b}b\bar{b}$通道中以4.2%的统计精度测量,在$HH\to b\bar{b}WW^\ast$通道中以14%的精度测量。利用$HH\to b\bar{b}b\bar{b}$通道,三线性希格斯自耦合的预期精度约为5%。这些结果展示了高能缪子对撞机在精密希格斯物理方面的潜力。
英文摘要
A 10 TeV muon collider offers a powerful environment for precision studies of the Higgs sector through its large vector-boson-fusion production rates. This review presents projected sensitivities to single- and double-Higgs production cross sections, the Higgs boson mass, and the trilinear Higgs self-coupling. The projections are obtained from detailed simulations of the MUSIC detector, including machine-induced background, for a baseline configuration of two experiments, each collecting an integrated luminosity of 10 $\mathrm{ab}^{-1}$. The $H\to b\bar{b}$ and $H\to WW^\ast$ production cross sections can be measured with statistical precisions of 0.18% and 0.35%, respectively, while precisions of 2.6%, 4.2%, and 6.9% are expected for $H\toγγ$, $H\to ZZ^\ast$, and $H\toμ^+μ^-$. Combining the $H\to b\bar{b}$, $H\toγγ$, and $H\toμ^+μ^-$ channels yields an expected Higgs boson mass precision of about 19 MeV. Double-Higgs production can be measured with statistical precisions of 4.2% in the $HH\to b\bar{b}b\bar{b}$ channel and 14% in the $HH\to b\bar{b}WW^\ast$ channel. Using the $HH\to b\bar{b}b\bar{b}$ channel, the trilinear Higgs self-coupling can be determined with an expected precision of about 5%. These results demonstrate the potential of a high-energy muon collider for precision Higgs physics.
