Recent charmed baryon results at BESIII
چکیده انگلیسی
Using 567 pb-1 of e+e− collisions recorded at s=4.599 GeV with the BESIII detector, we report on first measurements of absolute hadronic branching fractions of Cabibbo-favored decays of Λc+ baryon with a double tag technique. A global least-square fitter is utilized to improve the measured precision. The branching fractions for twelve hadronic decay modes are significantly improved. We also report the first model-independent measurement of the absolute branching fraction B(Λc+→Λe+νe)=(3.63±0.38(stat))%, which is the most accurate result to date and improves the previous precision more than twofold.
