在非相对论量子色动力学（NRQCD）框架下，我们系统研究了自旋单态^1S_0和自旋三重态^3S_1顶偶素在未来缪子对撞机及Pb-Pb超周边碰撞（Pb-Pb UPC）中的包含与非包含产生过程。利用库仑加线性势并求解薛定谔方程，我们得到原点波函数为|R_{t\ar{t}}(0)|^2 = 2.507 GeV^3。我们计算了这两类过程的散射截面和各种运动学分布，并基于预期的积分亮度估算了相应的事件产额。我们的研究表明，通过上述过程探测顶偶素产生的前景不利。
英文摘要
In the framework of non-relativistic quantum chromodynamics (NRQCD), we systematically investigate the inclusive and exclusive production processes of spin-singlet \(^1S_0\) and spin-triplet \(^3S_1\) toponium at future muon colliders and in Pb--Pb ultraperipheral collisions (Pb--Pb UPC). Using the Coulomb-plus-linear potential and solving the Schrödinger equation, we obtain the wave function at the origin as $|R_{t\bar{t}}(0)|^2 = 2.507\ \text{GeV}^3$. The scattering cross sections and various kinematic distributions for two types of processes are calculated, and the corresponding event yields are estimated based on the expected integrated luminosities. Our study indicates that the detection prospects for toponium production through the aforementioned processes are unfavorable.
