Abstract
By analyzing of annihilation data taken at the center-of-mass energy with the BESIII detector, we determine the branching fractions of the inclusive decays and to be and , respectively, where denotes any possible particle combination. The first uncertainties are statistical, and the second are systematic. We also determine the branching fractions of the decays and their charge conjugate modes separately for the first time, and no significant asymmetry is observed.
