Production of charmed baryon ${\Lambda }_c(2860)$ via low energy antiproton-proton interaction

Abstract

In the present work, we study the production problem of the charmed baryon ${\Lambda }_c(2860{)}^{+}$ at $\overline{\mbox{P}}$ANDA. With the $J^P={\frac{3}{2}}^{+}$ assignment to ${\Lambda }_c(2860{)}^{+}$, an effective Lagrangian approach is adopted to calculate the cross section of $p\bar{p}\to {\Lambda }_c^{-}{\Lambda }_c(2860{)}^{+}$. The Dalitz plot analysis and the $D^{0}p$ invariant mass spectrum distribution are also given for the $p\bar{p}\to {\Lambda }_c^{-}{\Lambda }_c(2860{)}^{+}\to {\Lambda }_c^{-}p{D}^0$ process. The numerical results show that the total cross section may reach up to about 10 $\mu$b. With the designed luminosity of $\overline{\mbox{P}}$ANDA ($2\times10^{32}~\mbox{cm}^{-2}\mbox{s}^{-1}$), about $10^8$ ${\Lambda }_c(2860)$ events can be expected per day by reconstructing the final $p{D}^0$.
