Inclusive production of fully-charmed 1 +− tetraquark at B factory

Inspired by the recent discovery of the \begin{document}$ X(6900) $\end{document} meson in the \begin{document}$ {\mathsf{ LHCb}}$\end{document} experiment, we investigate the inclusive production rate of the \begin{document}$ C $\end{document} -odd fully-charmed tetraquarks associated with light hadrons at the \begin{document}$ B $\end{document} factory within the nonrelativistic QCD (NRQCD) factorization framework. The short-distance coefficient is computed at the lowest order of velocity and \begin{document}$ \alpha_s $\end{document} . Employing two different kinds of phenomenological models to approximately estimate the long-distance NRQCD matrix element, we predict the rate for the inclusive production of the \begin{document}$ 1^{+-} $\end{document} \begin{document}$ T_{4c} $\end{document} state and discuss the observation prospect of the \begin{document}$ {{\mathsf{Belle}}\; {\mathsf{2}}} $\end{document} experiment.
