标题： Holographic quark masses and radiative decays of heavy vector mesons

摘要： QCD的全息模型通过规范场中电流-电流关联函数的计算，提供了重矢量介子质量和电磁衰变常数的谱。 相反，重矢量介子的唯象学由使用非相对论近似的构成夸克模型描述。 通过应用非相对论量子力学中的Segre公式，我们从全息理论中推导出新的可观测量：构成夸克质量、三光子衰变宽度、强相互作用的有效精细结构常数以及混合的一光子和两胶子衰变宽度。 我们还推导了重夸克偶素径向激发态的三胶子衰变宽度、三光子衰变宽度和混合的一光子和两胶子衰变宽度，并将其与可用的实验数据进行了比较。 目前的结果揭示了AdS/QCD中介子光谱学的一个新范式。 显示英文摘要

摘要： Holographic models of QCD provide the spectrum of heavy vector meson masses and electromagnetic decay constants through bulk computations of the current-current correlation function. Conversely, the phenomenology of heavy vector mesons is articulated by the constituent heavy quark model utilizing a non-relativistic approximation. By applying the Segre formula from non-relativistic quantum mechanics, we derive new observables from holography: the constituent quark mass, the three-photon decay width, the effective fine structure constant of the strong interaction, and the mixed one-photon and two-gluon decay width. We also derive the three-gluon decay width, the three-photon decay width, and the mixed one-photon and two-gluon decay width for the radially excited states of heavy quarkonia and compare them with available experimental data. The present results reveal a new paradigm of meson spectroscopy in AdS/QCD.
