TL;DR

This paper reports new measurements of the branching fractions of the charmed baryon mbda_c^+ decays into various final states, providing precise relative values based on data from the CLEO-II detector.

Contribution

It provides the first precise measurements of the relative branching fractions for multiple mbda_c^+ decay modes using CLEO-II data.

Findings

Measured relative branching fractions for four decay modes.

Improved precision over previous measurements.

Data supports theoretical models of charmed baryon decays.

Abstract

Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon $\Lambda_c^+$ into $pK^-\pi^+\pi^0$, $p\bar{K}^0$, $p\bar{K}^0\pi^+\pi^-$, and $p\bar{K}^0\pi^0$, all measured relative to $pK^-\pi^+$. The relative branching fractions are $0.67\pm0.04\pm0.11, 0.46\pm0.02\pm0.04,0.52\pm0.04\pm0.05$, and $0.66\pm0.05\pm0.07$ respectively.
