Description
Elliptic flow and ridge-like correlation have been observed in heavy-ion collision and they are considered as important probes for understanding the hydrodynamic properties of Quark Gluon Plasma. The ridge and $v_{2}$ are also measured in $d+Au$ and $^{3}He+Au$ collisions at RHIC, and in $p+p$ and $p+Pb$ collisions at LHC, therefore these observation have raised a great interest whether a similar hot and dense matter observed in heavy ion collision is also formed in small systems or not. 510 GeV p+p collisions were operated at RHIC in 2013. So far in p+p collisions at 200 GeV, ridge-like signal have not been found yet. However, there is significant difference in the multiplicity between 510 GeV and 200 GeV, so comparison of the two energies could provide an important insight on multiplicity and collision energy dependent studies with small collision systems.
In this poster, we report current status of flow and long-range correlation studies in high-multiplicity $p+p$ collisions at $\sqrt{s_{NN}}=510$ GeV with various analysis methods including (1) 2-particle correlation, (2) event plane as well as (3) reference fitting methods, and possibly to compare with $p+p$ collisions at $\sqrt{s_{NN}}=200$ GeV and other small collision systems, such as $p+A$, $d+A$ and $^{3}He+A$ collisions at RHIC energies in PHENIX experiment.
