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.
