Based on 4.5 fb−1 e+e− collision data collected with BESIII detector at seven energy points between 4.600 and 4.699 GeV, the branching fractions for and were measured by means of single-tag method. The branching fractions of and are determined to be (1.57 ± 0.11stat ± 0.04syst) × 10−3 and (1.11 ± 0.20stat ± 0.07syst) × 10−3, with a statistical significance of greater than 10σ and 5.7σ, respectively. These results are consistent with the previous measurements by BESIII, LHCb and Belle, and the result of is the most precise to date.
