# Analysis of the hidden-bottom tetraquark mass spectrum with the QCD sum rules

## TL;DR

This paper uses QCD sum rules to systematically analyze the mass spectrum of ground state hidden-bottom tetraquarks, aiming to compare predictions with future experimental data to understand the nature of Z_b states.

## Contribution

It extends previous work by providing a systematic QCD sum rule analysis of hidden-bottom tetraquark masses, highlighting effective diquark configurations.

## Key findings

- Scalar, axialvector, and tensor diquark components are effective in forming the lowest tetraquark states.
- Predicted tetraquark masses can be tested against future experimental data.
- The study offers insights into the internal structure of Z_b states.

## Abstract

In this article, we extend our previous work to study the mass spectrum of the ground state hidden-bottom tetraquark states with the QCD sum rules in a systematic way. The predicted hidden-bottom tetraquark masses can be confronted to the experimental data in the future to diagnose the nature of the $Z_b$ states. In calculations, we observe that the scalar diquark states, the axialvector diquark states and the axialvector components of the tensor diquark state are all good diquarks in building the lowest tetraquark states.
