Abstract

In the present work we explore the production potential of Λc(2880)+\Lambda_c(2880)^+ at PANDA. With the JP=52+J^P=\frac{5}{2}^+ assignment to Λc(2880)+\Lambda_c(2880)^+, we calculate the differential and total cross sections of ppˉΛcΛc(2880)+p\bar{p}\to \Lambda_c^-\Lambda_c(2880)^+. We also perform the Dalitz plot analysis and give the pD0pD^0 invariant mass spectrum distribution of the process ppˉΛcpD0p\bar{p}\to \Lambda_c^-pD^0, where the signal and background contributions are considered. Our numerical results indicate that the production of Λc(2880)+\Lambda_c(2880)^+ may reach up to about 20 μ\mub. About 10710^7 events from the reconstruction of pD0pD^0 can be accumulated per day, if taking the designed luminosity (2×1032 \mboxcm2\mboxs12\times10^{32}~\mbox{cm}^{-2}\mbox{s}^{-1}) of PANDA.
