论文摘要
我们研究了从$λ_Cp $的两粒子动量相关函数测量的诱人重子与核子相互作用的限制的前景。相关函数是针对$λ_cn $和$σ_cn $交互作用计算的，这些相互作用已从$m_π的非物理质量的晶格QCD模拟中推断出，使用手性有效的磁场理论作为指南。此外，我们考虑了文献中的现象学$ y_c n $模型，以详细探讨结果对相互作用属性的敏感性。我们发现，正如某些现象学模型所预测的那样，对$λ_cp $相关函数的测量确实可以使人区分强烈的$λ_cn $ forct，以及当前可用的lattice simulations所建议的弱吸引人的相互作用。
We study the prospects for deducing constraints on the interaction of charmed baryons with nucleons from measurements of two-particle momentum correlation functions for $Λ_c p$. The correlation functions are calculated for $Λ_c N$ and $Σ_c N$ interactions that have been extrapolated from lattice QCD simulations at unphysical masses of $m_π=410-570$ MeV to the physical point using chiral effective field theory as guideline. In addition, we consider phenomenological $Y_c N$ models from the literature to explore the sensitivity of the results to the properties of the interaction in detail. We find that a measurement of the $Λ_c p$ correlation functions could indeed allow one to discriminate between strongly attractive $Λ_c N$ forces, as predicted by some phenomenological models, and a weakly attractive interaction as suggested by the presently available lattice simulations.
