## Abstracts

 Using?567pb?1?of?e+e??collisions recorded at?s√=4.599GeV?with the BESIII detector, we report first measurements of absolute hadronic branching fractions of Cabibbo-favored decays of the?Λ+c?baryon with a double-tag technique. A global least-square fitter is utilized to improve the measured precision. Among the measurements for twelve?Λ+c?decay modes, the branching fraction for?Λ+c→pK?π+?is determined to be?(5.84±0.27±0.23)%, where the first uncertainty is statistical and the second is systematic. In addition, the measurements of the branching fractions of the other eleven Cabbibo-favored hadronic decay modes are significantly improved.
