Charmed hadron production from secondary anti-proton + proton annihilations in p+A reactions at FAIR

Abstract

We present estimates for the production cross sections of exotic states (${\Lambda }_c,{\Sigma }_c,{\Xi }_c,D\mathrm{and}{D}_s$) from secondary $\overline{B}+B$ annihilations in p+A reactions from $E_{\mathrm{lab}}=10-30A$~GeV. We focus specifically on the newly planned hadron physics program of CBM at FAIR. These estimates for the production of exotic states are based on the achievable number of $\overline{B}+B$ annihilations and their invariant mass distributions calculated in the UrQMD transport model.
