摘要：

We present theoretical model comparison with published ALICE results for D-mesons (D-0, D+ and D*(+)) in p + p collisions at root s = 7 TeV and p + Pb collisions at root s(NN) = 5.02TeV. Event generator Heavy-Ion Jet Interaction Generator (HIJING), transport calculation of AMPT and calculations from Next-to-Leading Order (NLO)(MNR) and Fixed-Order Next-to-Leading-Logarithmic (FONLL) have been used for this study. We found that HIJING and AMPT model predictions are matching with published D-meson cross-sections in p + p collisions, while both under predict the same in p + Pb collisions. Attempts were made to explain the R-pPb data using NLO-pQCD(MNR), FONLL and other above mentioned models.
