论文摘要
The Future Circular Collider in the $\mathrm{e^{+}e^{-}}$ configuration offers the opportunity to significantly improve SM measurements with dedicated runs at the Z-pole, WW threshold, ZH (240 GeV), and $\mathrm{t}\bar{\mathrm{t}}$ threshold.在Z-Pole的$ 10^{5} $的统计信息约为$ 10^{5}，而在LEP上，FCC-EE将在per-mille级别提取强率$α__{s} $。 Parton淋浴研究从$ \ Mathrm {Zh}（{\ rightArrow} \ Mathrm {gg}）$中利用纯Gluon样品的研究将大大提高我们对Gluon辐射和碎片化的理解，直接影响Quark vs Gluon歧视研究。进一步的可能性包括在WW阈值下进行精确的强国研究和颜色重新连接研究。下面概述了FCC-EE的丰富精度QCD程序的某些元素。
The Future Circular Collider in the $\mathrm{e^{+}e^{-}}$ configuration offers the opportunity to significantly improve SM measurements with dedicated runs at the Z-pole, WW threshold, ZH (240 GeV), and $\mathrm{t}\bar{\mathrm{t}}$ threshold. With a factor of approximately $10^{5}$ more statistics at the Z-pole and $10^{4}$ at the WW threshold than at LEP, the FCC-ee will enable the extraction of the strong coupling $α_{s}$ at the per-mille level. Parton showering studies exploiting the pure gluon sample from $\mathrm{ZH}({\rightarrow} \mathrm{gg})$ will greatly improve our understanding of gluon radiation and fragmentation, directly impacting quark vs gluon discrimination studies. Further possibilities include precision hadronization studies and colour reconnection studies at the WW threshold. Some elements of the rich precision QCD program of the FCC-ee are outlined below.
