AI 中文摘要
相对论重离子碰撞中的飞秒关联技术为研究强子-强子相互作用及可能的奇特态提供了独特机会。本工作研究pΛ_c关联函数及其对与可能的$^3_{Λ_c}$H束缚态相关的低能NΛ_c相互作用的敏感性。基于夸克离域色屏蔽模型，构建了三种不同强度的相互作用场景，并在Koonin-Pratt形式论框架下计算了对应的自旋平均pΛ_c关联函数。结果表明，该关联函数对pΛ_c相互作用强度敏感，耦合道效应与S-D波混合会在关联信号中产生额外增强。这些发现提示，未来相对论重离子碰撞实验中的pΛ_c飞秒测量可为粲重子与核子间的相互作用提供重要约束，并为探索可能的重味超核提供指导。
英文摘要
The femtoscopic correlation technique in relativistic heavy-ion collisions provides a unique opportunity to investigate hadron-hadron interactions and possible exotic states. In this work, we study the $pΛ_c$ correlation function and its sensitivity to the low-energy $NΛ_c$ interaction related to possible $^3_{Λ_c}\mathrm{H}$ bound states. Based on the quark delocalization color screening model, three interaction scenarios with different strengths are constructed, and the corresponding spin-averaged $pΛ_c$ correlation functions are calculated within the Koonin--Pratt formalism. The results demonstrate that the correlation function is sensitive to the $pΛ_c$ interaction strength, with coupled-channel effects and $S$-$D$ wave mixing producing additional enhancements in the correlation signal. These findings suggest that future $pΛ_c$ femtoscopic measurements at relativistic heavy-ion collision experiments can provide valuable constraints on the interaction between charmed baryons and nucleons and offer guidance for exploring possible heavy-flavor hypernuclei.
