标题： Comparative study of three-nucleon force models in nuclear matter

摘要： 我们使用微观多体布吕克纳-哈特里-福克（BHF）方法计算对称核物质和纯中子物质的每个粒子的能量，并采用阿贡纳V18（AV18）核子-核子（NN）势，同时补充了两种不同的三核子力模型，这些模型最近被构建以重现$^3$H、$^3$He 和$^4$He 核的结合能以及中子-氘双态散射长度。 我们发现，这些新的三核子力模型都无法同时再现对称核物质的经验饱和点以及三核子和四核子系统的特性。 显示英文摘要

摘要： We calculate the energy per particle of symmetric nuclear matter and pure neutron matter using the microscopic many-body Brueckner-Hartree-Fock (BHF) approach and employing the Argonne V18 (AV18) nucleon-nucleon (NN) potential supplemented with two different three-nucleon force models recently constructed to reproduce the binding energy of $^3$H, $^3$He and $^4$He nuclei as well as the neutron-deuteron doublet scattering length. We find that none of these new three-nucleon force models is able to reproduce simultaneously the empirical saturation point of symmetric nuclear matter and the properties of three- and four-nucleon systems.
