论文摘要
我们采用了有效的哈密顿量，其中包括横向和纵向限制以及与固定耦合常数的一链交换相互作用。通过在基础光量量化（BLFQ）中求解特征值方程，我们为价夸克群空间中的核子生成光前波函数（LFWF）。拟合模型参数，我们获得了电磁形式因子和质子半径的高质量描述，而结果却与中子的实验数据有些差异。
We employ an effective Hamiltonian that includes the transverse and longitudinal confinement and the one-gluon exchange interaction with fixed coupling constant. By solving the eigenvalue equation in basis light-front quantization (BLFQ), we generate the light-front wavefunctions (LFWFs) for the nucleon in the valence quark Fock space. Fitting the model parameters, we obtain high-quality descriptions of electromagnetic form factors and radius for proton while the results deviate somewhat from experimental data for neutron.
