标题： A sign of three-nucleon short-range correlation from an analysis of nuclear mass and short-range correlation probability

摘要： 三核短程关联（$3N$ SRC）代表了短距离下核动力学中一个罕见且有趣的部分，超越了双核短程关联（$2N$ SRC）。探索其存在性是当前和未来高能核实验以及核理论发展中的一大热点课题。 本研究中，我们通过分析核子数相关的原子核质量与核子处于$2N$SRC态的概率之间的关联，结合来自SLAC、CLAS和JLab Hall C合作组关于$^2$氢、$^3$氦、$^4$氦、$^9$锂、$^{12}$碳、$^{27}$铝、$^{56}$铁、铜、$^{197}$金以及$^{208}$铅的当前实验测量数据，发现在原子核内$3N$SRC 存在正相关信号。 在$2N$和$3N$的短程关联（SRC）中的核子有效质量也从分析中提取出来，这为研究核介质效应提供了一些参考。$3N$的 SRC 概率远小于$2N$的 SRC 概率，因此需要高亮度实验来确认其存在。 显示英文摘要

摘要： Three-nucleon short-range correlation ($3N$ SRC) represents a rare and intriguing part of the nuclear dynamics at short distance, beyond the two-nucleon short-range correlation ($2N$ SRC). To search its existence is a hot topic in the ongoing and future high-energy nuclear experiments and the developments of nuclear theory. In this study, we found a positive sign of $3N$ SRC in nuclei, by analyzing the correlation between the per-nucleon nuclear mass and the probability of a nucleon in $2N$ SRC state, with the current experimental measurements of $^2$H, $^3$He, $^4$He, $^9$Be, $^{12}$C, $^{27}$Al, $^{56}$Fe, Cu, $^{197}$Au and $^{208}$Pb from SLAC, CLAS, and JLab Hall C collaborations. The effective masses of the nucleons in $2N$ SRC and $3N$ SRC are also extracted from the analysis, which provide some references for the nuclear medium effect study. The probability of $3N$ SRC is much smaller than that of $2N$ SRC, thus requiring high-luminosity experiments to confirm its existence.
