Dihadron correlations in d+Aud+Au collisions from STAR

Dihadron correlations are reported for peripheral and central d+Aud+Au collisions at sNN=200 GeV from STAR. The ZYAM background-subtracted correlated yields are larger in central than peripheral collisions. The difference is mainly caused by centrality biases to jet-like correlations. Fourier coefficients of the raw dihadron correlations are also reported. It is found that the first harmonic coefficient is approximately inversely proportional to event multiplicity, whereas the second harmonic coefficient is approximately independent of event multiplicity.
