In the present work we explore the production potential of Λc(2880)+ at PANDA. With the JP=25+ assignment to Λc(2880)+, we calculate the differential and total cross sections of ppˉ→Λc−Λc(2880)+. We also perform the Dalitz plot analysis and give the pD0 invariant mass spectrum distribution of the process ppˉ→Λc−pD0, where the signal and background contributions are considered. Our numerical results indicate that the production of Λc(2880)+ may reach up to about 20 μb. About 107 events from the reconstruction of pD0 can be accumulated per day, if taking the designed luminosity (2×1032\mboxcm−2\mboxs−1) of PANDA.
