Texto completo: acesso restrito. p. 277–282We report the observation of the Cabibbo suppressed decay Ξc+→pK−π+ using data collected with the FOCUS spectrometer during the 1996–1997 Fermilab fixed target run. We find a Ξc+ signal peak of 202±35 events. We have measured the relative branching ratios BR(Ξ+c→pK−π+)/BR(Ξ+c→Ξ−π+π+)=0.234±0.047±0.022 and View the MathML source
