abstract
Using $567\rm{pb}^{-1}$ of $e^+e^-$ collisions recorded at $\sqrt{s}=4.599\rm{GeV}$ with the BESIII detector, we report first measurements of absolute hadronic branching fractions of Cabibbo-favored decays of the $\Lambda_{c}^{+}$ baryon with a double-tag technique. A global least-square fitter is utilized to improve the measured precision. Among the measurements for twelve $\Lambda_{c}^{+}$ decay modes, the branching fraction for $\Lambda_{c}^{+} \rightarrow pK^-\pi^+$ is determined to be $(5.84\pm0.27\pm0.23)\%$, 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.

From topological amplitudes to rescattering dynamics in charmed baryon decays
hep-ph 2025-07 conditional novelty 6.0 of 10
The authors build a bridge between topological and rescattering amplitudes for charmed baryon decays and claim the Koerner-Pati-Woo theorem fails, suggesting a measurement of Lambda_c^+ -> Sigma^+ K_S^0.
