Λc decays at BESIII
چکیده انگلیسی
Using 567pb−1e+e− collision data collected with the BESIII detector at a center-of-mass energy of s=4.599 GeV, near the Λc+Λ‾c− threshold, we report the 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 present the semi-leptonic decay B(Λc+→Λe+νe)=(3.63±0.38(stat.)±0.20(syst.))%. Preliminary results for Λμ+νμ and nKS0π+ decay modes are also reported, along with future prospects.
