标题： Flavor-Dependent Dynamical Spin-Orbit Coupling in Light-Front Holographic QCD: A New Approach to Baryon Spectroscopy

摘要： 本文中，我们提出了一种Light-Front全息量子色动力学（QCD）的新扩展，通过引入与味相关的动力学自旋-轨道势来研究自旋-轨道耦合对重子谱的影响。该势由全息坐标和夸克味调制，能够解释夸克的质量层次以及禁闭的非微扰动力学。通过引入随禁闭尺度指数衰减的耦合，我们捕捉了短程和远程自旋-轨道相互作用之间的相互作用，特别是在重夸克-轻夸克重子的情况下。与全息胶子场的可选耦合进一步丰富了模型，引入了非微扰QCD效应。由此产生的修正的光前波方程预测了与味相关的质量分裂和雷杰轨迹，为轻重子谱提供了更好的描述。我们讨论了实现方法、参数拟合以及实验验证的可检验预测，特别是对LHCb和Belle II观测到的重夸克重子。这种方法连接了轻夸克和重夸克的动力学，推进了重子谱全息建模的发展。 显示英文摘要

摘要： In this article, we propose a novel extension of Light-Front Holographic Quantum Chromodynamics (QCD) to study the effects of spin-orbit coupling on the baryon spectrum by introducing a flavor-dependent dynamical spin-orbit potential. This potential, modulated by the holographic coordinate and quark flavor, accounts for the mass hierarchy of quarks and the nonperturbative dynamics of confinement. By incorporating an exponentially decaying coupling that varies with the confinement scale, we capture the interplay between short-distance and long-distance spin-orbit interactions, particularly for heavy-light baryons. An optional coupling to holographic glueball fields further enriches the model, introducing nonperturbative QCD effects. The resulting modified light-front wave equation predicts flavor-dependent mass splittings and Regge trajectories, offering improved descriptions of both light and heavy baryon spectra. We discuss the implementation, parameter fitting, and testable predictions for experimental validation, particularly for heavy baryons observed at LHCb and Belle II. This approach bridges light and heavy quark dynamics, advancing the holographic modeling of baryon spectroscopy.
