论文摘要
我们证明了希格斯二抗衰变中的CP侵略性探针如何在未来的Lepton Colliders上腐烂，可以对弱尺度男性生成的测试具有重要的发现潜力。例如，圆形电子正电子对撞机的测量值可以排除大于$ 2.9^\ circ $（$ 5.6^\ circ $）的CP阶段，为68％（95％）C.L.假设Tau Lepton Yukawa耦合的大小的标准模型值。相反，这种敏感性将允许CP相位范围的82％$ [0,2π）$ $ 5 \，σ$ Discovery。未来的圆形对撞机-EE和国际线性对撞机的覆盖范围是可比的。结果，未来的Lepton Colliders可以建立Lepton风味的Electroweak Baryogenesewiss所需的CP违规，至少$ 3 \σ$敏感性。我们的结果表明，希格斯的工厂不仅是精确机器，而且还可以使$ \ mathcal o（1）$测量新物理学以外的标准模型。
We demonstrate how probes of CP-violating observables in Higgs di-tau decays at prospective future lepton colliders could provide a test of weak scale baryogenesis with significant discovery potential. Measurements at the Circular Electron Positron Collider, for example, could exclude a CP phase larger than $2.9^\circ$ ($5.6^\circ$) at 68% (95%) C.L. assuming the Standard Model value for magnitude of the tau lepton Yukawa coupling. Conversely, this sensitivity would allow for a $5\,σ$ discovery for 82% of the CP phase range $[0,2π)$. The reaches of the Future Circular Collider - ee and International Linear Collider are comparable. As a consequence, future lepton colliders could establish the presence of CP violation required by lepton flavored electroweak baryogenesis with at least $3\,σ$ sensitivity. Our results illustrate that Higgs factories are not just precision machines but can also make $\mathcal O(1)$ measurement of the new physics beyond the Standard Model.
