论文摘要
核子特性和结构应通过核子之间的短距离相关（SRC）来修饰。通过分析SRC比率数据，我们在假设SRC核子质量在不同的核中是通用的，我们提取SRC对中的核子质量和氘中PN-SRC对的预期数。两个核子SRC对的核子质量为$ m _ {\ text {src}} = 852 \ pm 18 $ meV，而deuterium中的pn-src对数为$ n^{\ text {d}}}}}强烈重叠的核子的质量不足可以通过对QCD中质量的痕量异常贡献或MIT袋模型中的真空能量来解释。
The nucleon properties and structure should be modified by short-range correlations (SRC) among nucleons. By analyzing SRC ratio data, we extract the mass of nucleon in the SRC pair and the expected number of pn-SRC pairs in deuterium, under the assumption that the SRC nucleon mass is universal in different nuclei. The nucleon mass of a two-nucleon SRC pair is $m_{\text{SRC}}=852\pm 18$ MeV, and the number of pn-SRC pairs in deuterium is $n^{\text{d}}_{\text{SRC}}=0.021\pm 0.005$. The mass deficit of the strongly overlapping nucleon can be explained by the trace anomaly contribution to the mass in QCD or alternatively by the vacuum energy in the MIT bag model.
