d+Au (min. bias) nuclear modification factor (I)

• No suppression observed in min.

• bias d+Au reactions (Ncoll= 8.4±0.4)

• Neutral pions: RdAu ~ 1.1

• (Slight enhancement with

• respect to collision scaling)

• Apparent decreasing trend

• above 8 GeV/c

• Charged hadrons: RdAu ~ 1.4

• (Larger enhancement)

• ~ flat between 3 – 8 GeV/c
