Abstract: (Elsevier)

We present first measurements of the evolution of the differential transverse momentum correlation function, C , with collision centrality in Au + Au interactions at sNN=200 GeV . This observable exhibits a strong dependence on collision centrality that is qualitatively similar to that of number correlations previously reported. We use the observed longitudinal broadening of the near-side peak of C with increasing centrality to estimate the ratio of the shear viscosity to entropy density, η/s , of the matter formed in central Au + Au interactions. We obtain an upper limit estimate of η/s that suggests that the produced medium has a small viscosity per unit entropy.
