Description
The BESIII detector accumulated 567 pb-1 data at the center-of-mass energy of 4.599 GeV, which is the world's largest e+e- collision sample at the Lambda_c pair threshold. By analyzing this data sample, we report the determinations of the absolute branching fractions of the Λc semi-leptonic decay and 12 hadrnoic decays.The precisions of these absolute branching fractions for these decays are improved significantly.
