摘要：

本工作研究了在FCC和S $pp$ C多TeV对撞机上发现、观测和排除具有γ +喷注末态的激发态$u$和$d$夸克的可能性。FCC和S $pp$ C对撞机的实验结果表明，激发态$u$和$d$夸克的能量分别为42.1 TeV和55.2 TeV（$u^\star$），30.3 TeV和39.4 TeV（$d^\star$），42.3 TeV和55.5 TeV（m $_{u^\star}$ = m $_{d^\star}$）。研究了激发态夸克复合标度的确定问题，这将达到多PeV水平。除了这些分析，自由参数（$f_s,\;f\;\text{and}\; f^\prime$）从0.1左右扫描到1，表明激发夸克可以发现在几十TeV的甚至耦合常数低于0.1。

英文摘要：

Potential discovery, observation and exclusion limits of excited $u$ and $d$ quarks with gamma+jet final state are researched at the multi-TeV scale colliders, FCC and S$pp$C in this work. Both colliders, FCC and S$pp$C, show that excited $u$ and $d$ quarks could be discovered up to 42.1 TeV and 55.2 TeV for $u^\star$, 30.3 TeV and 39.4 TeV for $d^\star$ and 42.3 TeV and 55.5 TeV mass values for degenerate case (m$_{u^\star}$ = m$_{d^\star}$), respectively. Determination of excited quarks compositeness scale is examined, which will be up to multi-PeV level. Beside these analysis, free parameters ($f_s,\;f\;\text{and}\; f^\prime$) are scanned from around 0.1 up to 1 that show excited quark could be discovered at dozens of TeV with even coupling constants under 0.1.
