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

In this article, we take the scalar diquark and antidiquark operators as the basic constituents, construct the $C{\gamma }_5\otimes {}_{\mu }\otimes {\gamma }_{5}C$ type tetraquark current to study the $Y(10750)$ with the QCD sum rules. The predicted mass $M_Y=10.75\pm 0.10\mathrm{G}\mathrm{e}\mathrm{V}$ and width $\Gamma_Y= 33.60^{+16.64}_{-9.45},{\rm{MeV}}$supportassigningthe$Y(10750)$ to be the diquark-antidiquark type vector hidden-bottom tetraquark state, which has a relative P-wave between the diquark and antidiquark constituents.
