摘要

在这项研究中，我们分析了统一麻省理工包模型中三重五夸克的质量和衰变。我们构建了三重五夸克的色旋波函数，并使用数值变分法计算了这些系统的所有基态质量。通过剔除构型 spsce 中的散射态，我们计算了各衰变通道相对于紧凑五夸克态最大宽度的衰变宽度比，得到了三重五夸克系统的主要衰变模式。

Masses and decays of triply-heavy pentaquarks* * D. J. is Supported by the National Natural Science Foundation of China (12165017)

In this study, we analyzed masses and decays of triply-heavy pentaquarks

in the unified MIT bag model. We construct the color-spin wave functions of the triply-heavy pentaquarks and use the numerical variational method to compute all the ground-state masses of these systems. By excluding the scattering states in configuration spsce, we computed the decay width ratios of each decay channel relative to the maximum width for the compact pentaquark states, obtaining the main decay modes of the triply-heavy pentaquark systems.
