我们计算了 AdS5 x S5 上定义的 QCD 全息对偶中的光强子光谱，该对偶在短距离下具有共形行为，在大夸克间距下具有限制性。通过弦模式与强子价态福克态插值算子维数的对应关系来识别特定的强子。更高轨道的激发与 AdS 背景波动的量子相匹配。由于仅使用一个参数，即 QCD 标度 Lambda（QCD），因此与物理状态模式的一致性非常显着。特别地，δ与核子轨迹的比率由贝塞尔函数的零点比率确定。
We compute the spectrum of light hadrons in a holographic dual of QCD defined on AdS5 x S5 which has conformal behavior at short distances and confinement at large interquark separation. Specific hadrons are identified by the correspondence of string modes with the dimension of the interpolating operator of the hadron's valence Fock state. Higher orbital excitations are matched quanta to quanta with fluctuations about the AdS background. Since only one parameter, the QCD scale Lambda(QCD), is used, the agreement with the pattern of physical states is remarkable. In particular, the ratio of delta to nucleon trajectories is determined by the ratio of zeros of Bessel functions.
