Nuclear modification factor $\RpPb$ of prompt non-strange D mesons in p--Pb collisions at $\sqrtsNN=5.02 \tev$. In the left panel, the data are compared with calculations of theoretical models that include only CNM effects: CGC , FONLL with EPPS16 nPDFs , a LO pQCD calculation (Vitev et al.) , and a calculation based on incoherent multiple scatterings (Kang et al.) . In the right panel, the predictions of the Duke and POWLANG transport models are compared with the measured D-meson $\RpPb$ The vertical bars and the empty boxes represent the statistical and systematic uncertainties The black-filled box at $\RpPb=1$ represents the normalisation uncertainty. | |
