论文摘要
Hadron的光线函数使我们能够计算广泛的物理可观察物。但是,波函数本身无法测量。我们讨论了使用有效的哈密顿量在横向和纵向方向以及具有明确的单网格交换的有效模型的有效的哈密顿量中获得的Quarkonia的最新结果。特别是,我们专注于基础膨胀的数值收敛,以及光前波函数的渐近行为。我们还说明,对于具有不等夸克质量的介子,轻率波函数的最大值以非平凡的方式取决于价夸克质量差异。
The light-front wave functions of hadrons allow us to calculate a wide range of physical observables; however, the wave functions themselves cannot be measured. We discuss recent results for quarkonia obtained in basis light-front quantization using an effective Hamiltonian with a confining model in both the transverse and longitudinal directions and with explicit one-gluon exchange. In particular, we focus on the numerical convergence of the basis expansion, as well as the asymptotic behavior of the light-front wave functions. We also illustrate that, for mesons with unequal quark masses, the maxima of the light-front wave functions depend in a non-trivial way on the valence quark-mass difference.
