Abstract
In the CERN NA32 experiment a high-resolution silicon vertex detector and a purely topological approach were used to collect a clean sample of A(c)+ decays into pK-pi+ with or without additional neutral particles. We study the subresonant structure of the LAMBDA(c)+ peak obtaining BR (LAMBDA(c)+ --> pKBAR*0(892)) = 0.35(-0.07)0.06 +/-0.03 with respect to the total LAMBDA(c)+ --> pK-pi+ decay. We also determine branching ratios for some channels with neutral decay products, namely BR(LAMBDA(c)+ --> pK-pi+pi0)=0.73+/-0.12+/-0.05 and BR(LAMBDA(c)+ --> pK-pi+pi0pi0)=0.16+/-0.07+/-0.03, again with respect to the total LAMBDA(c)+ --> pK-pi+decay.
