Description:
By analyzing 2.93 fb −1 data collected at the center-of-mass energy ##IMG## [http://ej.iop.org/images/1674-1137/40/11/113001/cpc20161102ieqn1.gif] with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D + → K̅ 0 e + ν e to be ℬ( D + → K̅ 0 e + ν e ) = (8.59 ± 0.14 ± 0.21)% using ##IMG## [http://ej.iop.org/images/1674-1137/40/11/113001/cpc20161102ieqn71.gif] , where the first uncertainty is statistical and the second systematic. Our result is consistent with previous measurements within uncertainties..
