Abstract:
We report the observation of the Cabibbo suppressed decay Xi_c^+ -> p K- pi+ using data collected with the FOCUS spectrometer during the 1996--97 Fermilab fixed target run. We find a Xi_c^+ signal peak of 202 +/- 35 events. We have measured the relative branching ratios BR(Xi^+_c -> p K- pi+)/BR(Xi^+_c -> Xi^- pi+ pi+) = 0.234 +/- 0.047 +/- 0.022 and BR(Xi^+_c -> p \bar{K}^*(892)^0)/BR(Xi^+_c -> p K- pi+) = 0.54 +/- 0.09 +/- 0.05.
