论文摘要
我们已经检查了对未来的MUON撞机的双霍顿产生中对轴状粒子（ALP）耦合的敏感性。解决了$μ^+μ^ - $ 3 TEV，14 TEV和100 TEV的碰撞。提出了差分横截面与最终光子和总横截面的不变质量相对于最小双光子不变质量的质量。我们得出了ALP仪玻色子耦合的排除区域。获得的边界比ALP质量区域10 GEV的当前实验边界强得多-10 TEV。估计了ALP柱玻色子耦合的部分波浪单位性约束。我们已经表明，在本文中研究的ALP耦合区域中没有违反单位性。
We have examined the sensitivity to the axion-like particle (ALP) couplings to electroweak gauge bosons in the diphoton production at a future muon collider. The collisions at the $μ^+ μ^-$ energies of 3 TeV, 14 TeV, and 100 TeV are addressed. The differential cross sections versus the invariant mass of the final photons and total cross section versus minimal diphoton invariant mass are presented. We have derived the exclusion regions for the ALP-gauge boson coupling. The obtained bounds are much stronger than the current experimental bounds in the ALP mass region 10 GeV -- 10 TeV. The partial-wave unitarity constraints on the ALP-gauge boson coupling are estimated. We have shown that the unitarity is not violated in the region of the ALP coupling studied in the present paper.
