基于矩阵模型的三体核力
Three-Body Nuclear Forces from a Matrix Model
摘要：
本文利用我们与P. Yi提出的全息QCD核矩阵模型计算了短距离下的三体核力。我们发现，在短距离的三体力是排斥（a）对齐的三个中子的平均自旋，（b）对齐的质子-质子-中子/质子-中子-中子。这些结果表明，在中子的稠密态，如中子星的核，或氦-3/氚核中，排斥力比仅用二体力估计的要大。
英文摘要：
We compute three-body nuclear forces at short distances by using the nuclear matrix model of holographic QCD proposed in our previous paper with P. Yi. We find that the three-body forces at short distances are repulsive for (a) aligned three neutrons with averaged spins, and (b) aligned proton-proton-neutron / proton-neutron-neutron. These indicate that in dense states of neutrons such as cores of neutron stars, or in Helium-3 / tritium nucleus, the repulsive forces are larger than the ones estimated from two-body forces only.
