PANN: Partial-wave analysis of nucleon–nucleon scattering in wide-energy region

Abstract
PANN is a partial-wave analysis program which can be used to determine the complex scattering amplitudes of elastic nucleon-nucleon scattering by fitting the experimental data on many kinds of observables. It is able to apply for an analysis in the wide energy region such as a few MeV to approximately 10 GeV. In PANN, the higher partial-wave amplitudes for the analysis in the low energy region (<1 GeV) are given by the one-pion exchange amplitude, and the ones in the high-energy region of sev...

Nature of problem
Partial-wave analysis (PWA) is a model independent method to determine the scattering amplitudes by means of fitting the experimental data on many kinds of observables. PANN carries out the energy-independent PWA of nucleon-nucleon scattering [1]. The obtained phase-shifts can be used to construct the potential model at low energies and to determine the coupling constants of the interactions in various models for nucleon-nucleon system at intermediate energies [2]. Unlike the usual PWA program, ...

摘要
PANN是一款部分波分析程序，可用于通过拟合多种可观测量的实验数据来确定弹性核子-核子散射的复散射振幅。该程序适用于广泛能量区域的分析，例如从几兆电子伏特至约10兆电子伏特。在PANN中，低能区（<1 GeV）的分析中使用的较高部分波振幅由单π介子交换振幅提供，而高能区的振幅则由其他机制产生。

问题性质
部分波分析（PWA）是一种独立于模型的方法，通过拟合多种可观测量的实验数据来确定散射振幅。PANN执行核子-核子散射的能量无关PWA [1]。获得的相位移可用于构建低能区的势模型，并确定中能区核子-核子系统各种模型中相互作用的耦合常数 [2]。与常规PWA程序不同，...
