Abstract
In this work we evaluate the production rate of the charmed baryon
\$Łambda\_c(2940)^+\$ at PANDA. For possible assignments of \$Łambda\_c(2940)^+\$:
\$J^P=1/2^\pm\$, \$3/2^\pm\$ and \$5/2^\pm\$, the total cross section of \$pp\to
Łambda\_c Łambda\_c(2940)^+\$ is estimated, which may exceed 1 nb. With
the designed luminosity (\$2\times10^-32\$cm\$^-2\$/s) of PANDA, our estimate
indicates that ten thousand events per day if \$Łambda\_c(2940)^+\$ is of
\$J^P=1/2^+\$ or \$10^8\$ per day if it is of \$J^P=5/2^+\$ can be expected. Those
values actually set the lower and upper limits of the \$Łambda\_c(2940)^+\$
production. In addition, we present the Dalitz plot and carry out a rough
background analysis of the \$Łambda\_c(2940)^+\$ production in the \$pp\to
D^0 pŁambda\_c\$ and \$pp\Sigma\_c^0,++\pi^+,-Łambda\_c\$
processes, which would provide valuable information for accurate determination
of the \$Łambda\_c(2940)^+\$ identity.
