论文摘要
在这项工作中提出了研究BESIII和类似$ e^+ E^ - $ E^+ E^ - $ E^+ E^ - $ E^+ E^ - $ colliders的超声核/核子相互作用的前景。利用在Besiii收集的100亿美元$ J/ψ$和27亿$ψ（3686）$衰减产生的大量超子，可以通过在Hyperons和beaseii detector的密集对象之间的散射来测量几种特定的弹性或无弹性 - 核反应的横截面。随后，可以通过进一步的现象学计算来提取相应的超核相互作用的横截面。此外，也可以通过本文中提出的方法研究抗Hyperon和核/核子之间的相互作用，包括散射和歼灭。结果肯定会受益于超核/核子相互作用的精确探针，并为研究强烈相互作用的潜力，颜色限制的起源，baryon-baryon相互作用的统一模型和中子星的内部结构提供了约束。此外，在这项工作中讨论并估算了未来超级tau-Charm工厂（STCF）的相应研究的理想前景。
The prospects to study hyperon-nuclei/nucleon interactions at BESIII and similar $e^+ e^-$ colliders are proposed in this work. Utilizing the large quantity of hyperons produced by the decay of 10 billion $J/ψ$ and 2.7 billion $ψ(3686)$ collected at BESIII, the cross sections of several specific elastic or inelastic hyperon-nuclei reactions can be measured via the scattering between the hyperons and the nucleus in the dense objects of BESIII detector. Subsequently, the cross sections of corresponding hyperon-nucleon interactions are able to be extracted with further phenomenological calculation. Furthermore, the interactions between antihyperon and nuclei/nucleon, including scattering and annihilation, can also be studied via the method proposed in this paper. The results will definitely benefit a lot the precise probe of the hyperon-nuclei/nucleon interactions and provide constraints for the studies of the potential of strong interaction, the origin of color confinement, the unified model for baryon-baryon interactions, and the internal structure of neutron stars. In addition, the desirable prospects of corresponding studies in the future Super Tau-Charm Factory (STCF) are discussed and estimated in this work.
