By analyzing 2.93 fb^−1 data collected at the center-of-mass energy with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D^+ → K̅0 e^+ν_e to be ℬ(D^+ → K̅0 e^+ν_e) = (8.59 ± 0.14 ± 0.21)% using , where the first uncertainty is statistical and the second systematic. Our result is consistent with previous measurements within uncertainties.

Abstract
By analyzing 2.93 fb^−1 data collected at the center-of-mass energy with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D^+ → K̅0 e^+ν_e to be ℬ(D^+ → K̅0 e^+ν_e) = (8.59 ± 0.14 ± 0.21)% using , where the first uncertainty is statistical and the second systematic. Our result is consistent with previous measurements within uncertainties.File in questo prodotto:
