标题： Spectrum of light- and heavy-baryons

摘要： 采用保对称性的截断方法处理强相互作用束缚态方程，用于计算基态$J=1/2^+$、$3/2^+$和$(qq^\prime q^{\prime\prime})$条件下的重子谱，其中$q, q^\prime, q^{\prime\prime} \in \{u,d,s,c,b\}$及其第一正宇称激发态和宇称伙伴。 通过两个参数，成功描述了已知的 39 个此类状态的光谱，计算值与实验值的平均绝对相对偏差为 3.6(2.7)%。 以此为基础，进一步利用该框架预测了尚未被实验证实的 90 个状态的质量。 显示英文摘要

摘要： A symmetry-preserving truncation of the strong-interaction bound-state equations is used to calculate the spectrum of ground-state $J=1/2^+$, $3/2^+$ $(qq^\prime q^{\prime\prime})$-baryons, where $q, q^\prime, q^{\prime\prime} \in \{u,d,s,c,b\}$, their first positive-parity excitations and parity partners. Using two parameters, a description of the known spectrum of 39 such states is obtained, with a mean-absolute-relative-difference between calculation and experiment of 3.6(2.7)%. From this foundation, the framework is subsequently used to predict the masses of 90 states not yet seen empirically.
