本文用几种精确的溶质散射模型说明了从反应数据中提取强子共振的内在困难。本文用有限体积哈密顿方法预测了两个介子交换反应的能谱。在一个三通道模型，和通道，我们显示的优势，有限体积哈密顿方法的方法使用Lüscher公式来测试格点QCD计算旨在预测核子共振。我们讨论了必要的步骤，使用ANL-Osaka八通道哈密顿量来预测的光谱测试的LQCD计算确定的激发核子态不变的质量GeV。
The intrinsic difficulties in extracting the hadron resonances from reaction data are illustrated by using several exactly solublescattering models. The finite-volume Hamiltonian method is applied to predict spectra using two meson-exchange Hamiltonians ofreactions. Within a three-channel model with,andchannels, we show the advantage of the finite-volume Hamiltonian method over the approach using the Lüscher formula to test Lattice QCD calculations aimed at predicting nucleon resonances. We discuss the necessary steps for using the ANL-Osaka eight-channel Hamiltonian to predict the spectra for testing the LQCD calculations for determining the excited nucleon states up to invariant massGeV.
