在本研究中，我们探究了三重重子（THBs）的基态质量、磁矩、跃迁磁矩、辐射衰变以及重味到重味的半轻衰变率，包括其对应的分支比。所涉及重子的基态质量通过在超中心组分夸克模型（hCQM）内数值求解六维超径向薛定谔方程得到，该模型包含超库仑势、线性禁闭势以及自旋相关相互作用。电磁性质利用重子的自旋-味波函数和有效组分夸克质量计算。半轻 $b \ ightarrow c$ 衰变宽度在重夸克自旋对称性框架下利用伊苏尔-怀斯函数计算，进而确定对应的分支比。
英文摘要
In this study, we investigate the ground-state masses, magnetic moments, transition magnetic moments, radiative decays, and heavy-to-heavy semileptonic decay rates, including their corresponding branching fractions of triply heavy baryons (THBs). The ground-state masses of the involved baryons are evaluated by numerically solving the six-dimensional hyperradial Schrödinger equation within the hypercentral constituent quark model (hCQM), incorporating both hyper-Coulomb and linear confinement potentials along with spin-dependent interactions. The electromagnetic properties are calculated using the spin-flavour wave functions and the effective constituent quark masses of the baryon. The semileptonic $b \rightarrow c$ decay widths are computed using the Isgur--Wise function within the heavy-quark spin symmetry, from which the corresponding branching ratios and lepton flavour universality ratios are also determined.
