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

Inspired by the recent discovery of the X(6900) meson in the LHCb experiment, we investigate the inclusive production rate of the C-odd fully-charmed tetraquarks associated with light hadrons at the B factory within the nonrelativistic QCD (NRQCD) factorization framework. The short-distance coefficient is computed at the lowest order of velocity and alpha(s). 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 1(+-) T-4c state and discuss the observation prospect of the Belle 2 experiment.

Automated summary

This study investigates the inclusive production rate of C-odd fully-charmed tetraquarks associated with light hadrons at the B factory, using the nonrelativistic QCD (NRQCD) factorization framework. The prediction for the inclusive production rate of the 1(+-) T-4c state and the observation prospect of the Belle 2 experiment are discussed based on the computations at the lowest order of velocity and alpha(s).
