Abstract
We optimize $\Delta$-full nuclear interactions from chiral effective field theory. The low-energy constants of the contact potentials are constrained by two-body scattering phase shifts, and by properties of bound-state of $A=2$ to $4$ nucleon systems and nuclear matter. The pion-nucleon couplings are taken from a Roy-Steiner analysis. The resulting interactions yield accurate binding energies and radii for a range of nuclei from $A=16$ to $A=132$, and provide accurate equations of state for nuclear matter and realistic symmetry energies. Selected excited states are also in agreement with data.
我们从手性有效场理论出发,优化了$\Delta$-满核相互作用。接触势的低能常数受两体散射相移、A=2 ~ 4$核子系统和核物质束缚态性质的限制。介子-核子耦合取自罗伊-斯坦纳分析。由此产生的相互作用为$ a =16$到$ a =132$范围内的原子核提供了精确的结合能和半径,并提供了核物质和真实对称能的精确状态方程。所选择的激发态也与数据一致。
