Abstract

We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ⁺_c→pK^- π⁺. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600GeV/c Σ^- beam. The branching fractions of the decay relative to the Cabibbo-favored Ξ+c→Σ⁺K_-π⁺ and Ξ⁺_c→Ξ^-π+π⁺ are measured to be B(Ξ⁺_c→pK^-π⁺)/B(Ξ⁺_c→Σ⁺K^-π⁺)=0.22±0.06±0.03 and B(Ξ+c→pK^-π+)/B(Ξ+c→Ξ^-π+π+)=0.20±0.04±0.02, respectively.

N2 - We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ+c→pK- π+. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600GeV/c Σ- beam. The branching fractions of the decay relative to the Cabibbo-favored Ξ+c→Σ+K-π+ and Ξ+c→Ξ-π+π+ are measured to be B(Ξ+c→pK-π+)/B(Ξ+c→Σ+K-π+)=0.22±0.06±0.03 and B(Ξ+c→pK-π+)/B(Ξ+c→Ξ-π+π+)=0.20±0.04±0.02, respectively.
