Description
In small asymmetric collision systems such as $^{3}He$+Au, precision measurements of the pseudorapidity dependence of the number of charged particles ($N_{charge}$) and the second order flow coefficient ($v_{2}$) have not been made. Nominally, $v_{2}$ is expected to be a monotonically decreasing function of rapidity from the Au going direction to the $^{3}He$ going direction. PHENIX's Silicon Vertex Detector (VTX) has a wide mid-pseudorapidity coverage ($eta$ < |1.5|) which allows for the measurement of $dN_{charge}$/d$eta$. When the VTX is coupled with information from PHENIX's forward detectors in the Au going direction, such as the MPC (-3.8 < $eta$ < -3.1), a measurement of $v_{2}$ in several $eta$ bins can be made.
This poster will present the latest status of analysis of the $dN_{charge}$/d$eta$ and $v_{2}$ pseudorapidity dependence in $^{3}He$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV with the PHENIX detector at RHIC. We will also show comparisons to hydrodynamic model calculations. We will also give the current status of similar analyses in p+Au and high multiplicity p+p collisions at 200 GeV.
