  <dc:description>We report the first observation of two Cabibbo-suppressed ecay modes, Xi(+)(c) -&gt; Sigma(+)pi(-)pi(+) and Xi c+ -&gt; Sigma(-)pi(+)pi(+). We observe 59 +/- 14 over a background of 87, and 22 +/- 8 over a background of 13 events, respectively, for the signals. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600 Gev/c Sigma(-) beam. The branching ratios of the decays relative to the Cabibbo-favored Xi c+ -&gt; Xi(-)pi(+)pi(+) are measured to be B(Xi(+)(c) -&gt; Sigma(+)pi(-)pi(+))/B(Xi(+)(c) -&gt; Xi(-)pi(+)pi(+)) = 0.48 +/- 0.20, and B(Xi(+)(c) -&gt; Sigma(-)pi(+)pi(+))/B(Xi(+)(c) -&gt; Sigma(-)pi(+)pi(+)) = 0.18 +/- 0.09, respectively. We also report branching ratios for the same decay modes of the Delta(+)(c) relative to Delta(+)(c) -&gt; pK(-)pi(+.) (C) 2008 Elsevier B.V. All rights reserved.</dc:description>
