摘要

摘要在这项工作中，我们在麻省理工包的统一框架下研究了三重四夸克的质量和其他静态性质，其中包含了色磁相互作用和增强的结合能。计算了所有奇异态和非奇异态（基态）三重四夸克的质量、磁矩和电荷半径，表明所有三重四夸克都在各自的双介子阈值之上。我们还估算了这些四夸克的二重介子主要衰变通道的相对衰变宽度。

Triply heavy tetraquark states: masses and other properties

Abstract

In this work, we study masses and other static properties of triply heavy tetraquarks in the unified framework of the MIT bag which incorporates chromomagnetic interactions and enhanced binding energy. The masses, magnetic moments and charge radii of all strange and nonstrange (ground) states of triply heavy tetraquarks are computed, suggesting that all of triply heavy tetraquarks are above the respective two-meson thresholds. We also estimate relative decay widths of main decay channels of two-heavy mesons for these tetraquarks.
