用NN和3 N势模型求解三维束缚态Faddeev-Yakubovsky方程

Solutions of the bound state Faddeev-Yakubovsky equations in three dimensions by using NN and 3N potential models

M. R. Hadizadeh, Lauro Tomio, S. Bayegan

摘要:

最近开发的三维方法(无分波分解)被认为是调查解决方案的Faddeev-Yakubovsky积分方程在动量空间中的三体和四体束缚态,包括三体力。在结合能的计算中,考虑了自旋相关的核子-核子(NN)势模型(S $_{3}$,MT-I/III,YS-型和P $_{5.5}$ GL)和标量两介子交换三体势。目前报道的结果与通过其他技术获得的良好协议,证明了一种方法的优势,其中的形式主义是更加简化和易于管理的直接计算。

英文摘要:

A recently developed three-dimensional approach (without partial-wave decomposition) is considered to investigate solutions of Faddeev-Yakubovsky integral equations in momentum space for three- and four-body bound states, with the inclusion of three-body forces. In the calculations of the binding energies, spin-dependent nucleon-nucleon (NN) potential models (named, S$_{3}$, MT-I/III, YS-type and P$_{5.5}$GL) are considered along with the scalar two-meson exchange three-body potential. Good agreement of the presently reported results with the ones obtained by other techniques are obtained, demonstrating the advantage of an approach in which the formalism is much more simplified and easy to manage for direct computation.
