Decoding the double heavy tetraquark state $T^+_{cc}$

TL;DR

This paper analyzes the structure of the $T^+_{cc}$ tetraquark state observed by LHCb, exploring its implications for the existence of other doubly heavy tetraquark states using quark clustering models.

Contribution

It introduces a quark clustering perspective to interpret the $T^+_{cc}$ state and suggests the potential existence of additional compact doubly heavy tetraquarks.

Findings

Identification of the $T^+_{cc}$ as a deuteron-like state

Implication of other compact doubly heavy tetraquarks

Support for quark clustering as a useful framework

Abstract

We analyse the deuteron-like $T^+_{cc}$ state observed by the LHCb Collaboration from the perspective of the quark clustering. The $T^+_{cc}$ state implies the possible existence of other compact doubly heavy tetraquark states.
