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

Abstract

In this article, we take the scalar diquark and antidiquark operators as the basic constituents, construct the $C{\gamma }_5\otimes {\overleftrightarrow{\partial }}_{\mu }\otimes {\gamma }_{5}C$ type tetraquark current to study the $Y(10750)$ with the QCD sum rules. The predicted mass $M_Y=10.75\pm 0.10\mathrm{GeV}$ and width ${\Gamma }_Y=33.60_{-9.45}^{+16.64}\mathrm{MeV}$ 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.
