论文摘要
在这项工作中，我们提出了一个框架，该框架允许使用波包连续核方法解决FADDEEV方程进行三核子散射。我们使用文献中的结果进行系统的基准，并详细研究该方法相对于波包数量的收敛性。我们使用手性核子核子相互作用计算几种不同的弹性中子 - 脱氧散射横截面可观测物。 For the interaction $\text{N2LO}_{\text{opt}}$ we find good agreement with data for nucleon scattering-energies $E_\text{Lab} \leq 70$ MeV and a slightly larger maximum of the neutron analyzing power $A_y(n)$ at $E_\text{Lab} = 10$ MeV and 21 MeV compared with other interactions.这项工作是朝着系统纳入下一代核相互作用时系统地包含三个核子散射的第一步。
In this work we present a framework that allows to solve the Faddeev equations for three-nucleon scattering using the wave-packet continuum-discretization method. We perform systematic benchmarks using results in the literature and study in detail the convergence of this method with respect to the number of wave packets. We compute several different elastic neutron-deuteron scattering cross-section observables for a variety of energies using chiral nucleon-nucleon interactions. For the interaction $\text{N2LO}_{\text{opt}}$ we find good agreement with data for nucleon scattering-energies $E_\text{Lab} \leq 70$ MeV and a slightly larger maximum of the neutron analyzing power $A_y(n)$ at $E_\text{Lab} = 10$ MeV and 21 MeV compared with other interactions. This work represents a first step towards a systematic inclusion of three-nucleon scattering observables in the construction of next-generation nuclear interactions.
