标题： New QCD Sum Rules for In-Medium Nucleons

摘要： 新的核物质中核子的QCD求和规则是从自旋-1/2和自旋-3/2插值场的混合关联函数导出的。 这些求和规则允许独立于尚不清楚的四夸克凝聚态来确定核子的标量自能。 这些新求和规则与之前来自自旋-1/2插值器的核子求和规则一起分析，表明与相对论平均场现象学的预期一致。 我们在核物质饱和密度下找到$M^* = 0.68 \pm 0.08$ GeV 和$\Sigma_v = 0.31 \pm 0.06$ GeV。 显示英文摘要

摘要： New QCD sum rules for nucleons in nuclear matter are derived from a mixed correlation function of spin-1/2 and spin-3/2 interpolating fields. These sum rules allow a determination of the scalar self-energy of the nucleon independent of the poorly known four-quark condensates. An analysis of these new sum rules in concert with previous nucleon sum rules from spin-1/2 interpolators indicates consistency with the expectations of relativistic mean-field phenomenology. We find $M^* = 0.68 \pm 0.08$ GeV and $\Sigma_v = 0.31 \pm 0.06$ GeV at nuclear matter saturation density.
