The studies are based on samples of proton-lead and lead-proton collision data, corresponding to an integrated luminosity of 12.5 and 17.4 nb-1, respectively, collected by the LHCb detector in 2016. The Ξc+ events are reconstructed in the detector through the decay of the Ξc+ baryon in a proton, a kaon and a pion. The analysis is performed over the transverse momentum range 2.0 < pT < 12.0 GeV/c in the regions of rapidity from 1.5 to 4.0 and from -5.0 to -2.5. I present the measurements of the Ξc+ cross-section, production ratios of Ξc+/Λc+ and Ξc+/D0 and forward-backward asymmetry. The results are compared to the latest theoretical predictions. These measurements can provide important information on the hadronisation of charm hadrons, as well as on the hadron structure. Since the Ξc+ contains s quark, the enhancement can be an indication of Quark Gluon Plasma formation.","abstract_html":"In this thesis I report the studies of production of Ξc+, a baryon made of usc quarks in proton-lead collisions at a centre-of-mass energy 8.16 TeV measured with LHCb detector at CERN.
