标题： Convergence in charmonium structure: light-front wave functions from basis light-front quantization and Dyson-Schwinger equations

摘要： 我们系统地比较了通过两种互补的非微扰方法获得的J/ψ轻子前沿波函数：基底轻子前沿量子化（BLFQ）和Dyson-Schwinger方程（DSE）。 关键可观测量包括电荷形式因子、引力形式因子、光锥分布幅度、衰变常数和双光子跃迁形式因子。 尽管它们的理论基础和模型参数不同，但BLFQ和DSE的预测在所有可观测量上表现出惊人的一致。 这种一致性验证了这两种框架在研究J/ψ结构中的有效性，并突显了基于哈密顿量的——BLFQ——和基于拉格朗日量的——DSE——方法在处理非微扰QCD中的互补优势。 显示英文摘要

摘要： We present a systematic comparison of charmonium light-front wave functions obtained through two complementary non-perturbative approaches: Basis Light-Front Quantization (BLFQ) and Dyson-Schwinger Equations (DSE). Key observables include the charge form factor, gravitational form factors, light-cone distribution amplitudes, decay constants, and two-photon transition form factors. Despite their distinct theoretical foundations and model parameters, the predictions from BLFQ and DSE exhibit remarkable agreement across all observables. This convergence validates both frameworks for studying charmonium structure and highlights the complementary strengths of Hamiltonian-based -- BLFQ -- and Lagrangian-based -- DSE -- methods in addressing non-perturbative QCD.
