Abstract / Description:Dihadron angular correlations in $d$+Au collisions at sqrt{s_NN}=200 GeV are reported as a function of the measured zero-degree calorimeter neutral energy and the forward charged hadron multiplicity in the Au-beam direction. A finite correlated yield is observed at large relative pseudorapidity (\\Delta\\eta) on the near side (i.e. relative azimuth \\Delta\\phi\\sim0). This correlated yield as a function of \\Delta\\eta$ appears to scale with the dominant, primarily jet-related, away-side ($\\Delta\\phi\\sim\\pi) yield. The Fourier coefficients of the \\Delta\\phi correlation, V_n=\\langle\\cos n\\Delta\\phi\\rangle, have a strong \\Delta\\eta dependence. In addition, it is found that V_1 is approximately inversely proportional to the mid-rapidity event multiplicity, while V_2 is independent of it with similar magnitude in the forward ($d$-going) and backward (Au-going) directions.
