手征有效场论中子物质状态方程及四阶对称能分析

Analysis of the neutron matter equation of state and the symmetry energy up to fourth order of chiral effective field theory

Francesca Sammarruca, Randy Millerson

摘要:

我们目前的预测中子物质状态方程,从导致四阶的手征有效场论,使用最近开发的,准确的手征核子核子势。我们发现次级三中子力的影响是温和的和有吸引力的。我们还展示了顺序的对称性能量的预测,并讨论了其密度依赖关系的经验约束。

英文摘要:

We present predictions for the neutron matter equation of state, from leading to fourth order of chiral effective field theory, using recently developed, accurate chiral nucleon-nucleon potentials. We find the impact of subleading three-neutron forces to be mild and attractive. We also show order-by-order predictions for the symmetry energy, and discuss its density dependence in relation to empirical constraints.
