# Vector hidden-bottom tetraquark candidate: $Y(10750)$

## TL;DR

This paper uses QCD sum rules with a specific tetraquark current to analyze the $Y(10750)$, predicting its mass and width, and supports its classification as a vector hidden-bottom tetraquark with a P-wave structure.

## Contribution

It introduces a novel tetraquark current to study the $Y(10750)$ and predicts its properties, supporting its interpretation as a diquark-antidiquark vector tetraquark.

## Key findings

- Predicted mass of $Y(10750)$ is 10.75 GeV.
- Predicted width of $Y(10750)$ is approximately 33.6 MeV.
- Supports $Y(10750)$ as a P-wave vector hidden-bottom tetraquark.

## Abstract

In this article, we take the scalar diquark and antidiquark operators as the basic constituents, construct the $C\gamma_5\otimes\stackrel{\leftrightarrow}{\partial}_\mu\otimes \gamma_5C$ type tetraquark current to study the $Y(10750)$ with the QCD sum rules. The predicted mass $M_{Y}=10.75\pm0.10\,\rm{GeV}$ and width $\Gamma_Y= 33.60^{+16.64}_{-9.45}\,{\rm{MeV}}$ support assigning the $Y(10750)$ to be the diquark-antidiquark type vector hidden-bottom tetraquark state, which has a relative P-wave between the diquark and antidiquark constituents.
