Description
The $\phi$ production in high-energy heavy-ion collisions provides key
information on the hot and dense state of the strongly interacting matter
produced in such collisions. They are sensitive to the medium-induced effects
such as strangeness enhancement, modification of the resonance line shapes
and their relative production rates in leptonic and hadronic decay modes
linked to the chiral symmetry restoration. Measurements in the dilepton channels
are especially interesting since leptons interact only electromagnetically,
thus carrying the information from their production phase directly to the detector.
Measurements of $\phi$ production in $^3$He+Au collisions, a new collision system,
add to the existing results ($p$+$p$, $d$+Au and Cu+Au) which extends our ability
to have a systematic study of nuclear medium effects on $\phi$ production.
The PHENIX detector provides the capabilities to measure the $\phi$ production
in a wide range of transverse momentum and rapidity to study various cold nuclear
effects such as soft multiple parton rescattering and modification of the parton
distribution functions in nuclei.
In this poster, we report the current status of the $\phi$ meson production
measurement from $^3$He+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV.
