Heavy-flavored tetraquark states with the $QQ\bar{Q}\bar{Q}$ configuration

TL;DR

This paper investigates the mass spectrum and decay patterns of heavy-flavored tetraquark states with the $QQ\bar{Q}\bar{Q}$ configuration, identifying potential stable or narrow states that could aid experimental searches.

Contribution

It systematically analyzes the mass spectrum of heavy tetraquarks using the color-magnetic interaction, highlighting possible stable states in specific heavy quark combinations.

Findings

Possible stable or narrow states in $bb\bar{b}\bar{c}$ and $bc\bar{b}\bar{c}$ systems.

Identification of decay patterns for these tetraquarks.

Guidance for experimental searches of heavy exotic tetraquark states.

Abstract

In the framework of the color-magnetic interaction, we systematically investigate the mass spectrum of the tetraquark states composed of four heavy quarks with the $QQ\bar Q\bar Q$ configuration in this work. We also show their strong decay patterns. Stable or narrow states in the $bb\bar{b}\bar{c}$ and $bc\bar{b}\bar{c}$ systems are found to be possible. We hope the studies shall be helpful to the experimental search for heavy-full exotic tetraquark states.
