Measurement of the Branching Fractions of $Λ_{c}^{+}\to p\bar{K}n(π)$

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 $Λ_c^+$ into $pK^-π^+π^0$, $p\bar{K}^0$, $p\bar{K}^0π^+π^-$, and $p\bar{K}^0π^0$, all measured relative to $pK^-π^+$. 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.
