Abstract

In this work we evaluate the production rate of the charmed baryon Λc(2940)+ at PANDA. For possible assignments of Λc(2940)+: JP=1/2±, 3/2± and 5/2±, the total cross section of pp¯Λ¯cΛc(2940)+ is estimated, which may exceed 1 nb. With the designed luminosity (2×1032cm2/s) of PANDA, our estimate indicates that ten thousand events per day if Λc(2940)+ is of JP=1/2+ or 108 per day if it is of JP=5/2+ can be expected. Those values actually set the lower and upper limits of the Λc(2940)+ production. In addition, we present the Dalitz plot and carry out a rough background analysis of the Λc(2940)+ production in the pp¯D0pΛ¯c and pp¯Σc0,++π+,Λ¯c processes, which would provide valuable information for accurate determination of the Λc(2940)+ identity.
