pT dependence of the suppression (II)

Energy loss with LPM interference effect: (1) gives too much suppression at moderate pT, (2) does not give the observed ~flat pT dependence of RAA
Alternative 1: Let's test the Bethe-Heitler limit ...
Alternative 2: Let's add all other relevant nuclear effects ...
- Modified nuclear PDFs (aka "shadowing”)
- Initial-state pT broadening (aka "Cronin effect”)
