Description
The $\Xi_c^+$ baryon is an open charm state comprised of an up, strange, and charm quark. For its peculiar composition with the presence of the strange quark, studies of baryon-to-baryon ratio of $\Xi_c^+$ to $\Lambda_c^+$ can provide valuable information on charm hadronization mechanisms, and possibly observe strangeness enhancement in small systems. We present the first study of $\Xi_c^+$/$\Lambda^+_c$ ratio in proton lead and lead proton collisions at the $\sqrt{s} = 8.16$ TeV with the LHCb experiment. The baryons are reconstructed in their decay with a proton, a kaon, and a pion in about 30 $nb^{-1}$ of data. The results will be compared to existing measurements in other collision systems and at different energies, and to recent theoretical predictions.
