Nuclear modification factors:
- $R_{OO}$ (top panel)
- $R_{pO}$ (middle panel)
- $R_{OO}/R_{pO}^2$ (bottom panel
For each modification factor, data are accompanied by pQCD predictions at NLO from four different nPDFs (F. Jonas et al: arXiv:2602.15928)
$R_{OO}/R_{pO}^2$ is furthermore shown for two energy loss model predictions:
- Hybrid coupling approach (J. Solana et al., JHEP 09 (2015) 175)
- Cape Town model (C. Faraday and W. Horowitz, JHEP 11 (2025) 19)
