Vector hidden-bottom tetraquark candidate: Y(10750)

In this article, we take the scalar diquark and antidiquark operators as the basic constituents, and construct the begin{document}$Cgamma_5otimesstackrel{leftrightarrow}{partial}_muotimes gamma_5C$end{document} type tetraquark current to study Y(10750) with the QCD sum rules. The predicted mass begin{document}$M_{Y}=10.75pm0.10,rm{GeV}$end{document} and width begin{document}$Gamma_Y= 33.60^{+16.64}_{-9.45},{rm{MeV}}$end{document} support the assignment of Y(10750) as the diquark-antidiquark type vector hidden-bottom tetraquark state, with a relative P-wave between the diquark and antidiquark constituents.
