Dijets via high pT dihadron azimuthal correlations: pp, dAu

• Two-particle correlations: h±- – h±, p0,± – h±. Trigger: highest pT (leading) hadron.

• Associated  distribution (e.g. ”assorted”: 2 GeV/c < pTassoc < pTtrigger)

• Normalized to number of triggers:

• Clear near- ( ~ 0) and away- ( ~ p) side jet signals:
