Description
The high p$_T$ hadron suppression caused by the energy loss of partons traversing the hot and dense matter is found to be one of the evidences of Quark-Gluon-Plasma (QGP) formation in high-energy heavy-ion collisions.
Measurements in p+A and d+A collision systems have been considered as a control-experiment to study cold nuclear matter effects without QGP formation.
However, recent measurements of hydrodynamic flow behavior and long-range angular correlations in p+A, d+A, and high multiplicity p+p collisions have indicated that small but high-density systems could be produced in such collisions, although the minimum bias R$_{AA}$ is about unity.
$^3$He+Au collisions have been delivered at RHIC in 2014 in order to
perform a systematic study of small systems from p+p and d+Au to $^3$He+Au having different spacial anisotropy of initial states.
In this poster presentation, we report the current status of charged hadron production and two-particle correlation measurements in $^3$He+Au collisions at ${\sqrt{s_{NN}}}$ = 200 GeV. Obtained results are compared between different collision systems.
