In this paper, we have studied differential production cross section of charmed baryon as a function of in and p–Pb collisions at in the transverse momentum range of and , respectively. For this study, we compared PYTHIA 8 Monte Carlo simulations with the experimental results obtained by the ALICE Acharya et al. (Phys. Rev. C 104: 054905, 2021) and LHCb Aaij et al. (J. High Energ. Phys. 02: 102, 2019) collaborations. The transverse momentum spectra are plotted in the rapidity interval of for pp collisions, while in , and (forward) and (backward) rapidity intervals for p–Pb collisions by using PYTHIA 8 Monash tune and CR tunes (modes 0, 2 and 3). Baryon-to-meson ratios as a function of and rapidity are shown. The nuclear modification factor for at mid-rapidity calculated from the cross sections in and p–Pb collisions is also presented. Both the magnitude and trend of distributions of and ratios verses as experimentally observed are well explained by PYTHIA 8 tunes that implement color reconnection beyond leading-color approximations.
