h±,p0 high-pT spectra: peripheral vs. central colls.
- Comparison to scaled N+N reference and to pQCD calcul. with kT+shadowing:
- ¥ Peripheral collisions well described
- ¥ Suppression at pT>1 GeV/c in central colls. not described (calculations including constant dE/dx=0.25 GeV/fm loss compatible with data)
