Description
Forward and backward rapidity regions are rich laboratories to explore several effects which happens to a probe before and after its hard scattering. The large rapidity region may also test a different dynamics for strangeness enhancement seen in heavy ion collisions at RHIC and LHC. The PHENIX experiment has a long history of large rapidity measurements with the muon spectrometers covering 1.2<|𝜂|<2.2 and a forward calorimeter (MPC) covering 3.1<| 𝜂 |<3.8. The addition of a pre-shower detector, the MPC-ex in front of the MPC, allows the identification of $\pi^{0}$ in a broad momentum range covering a Bjorken-x region between 10$^{-3}$ − 10$^{−2}$. This talk will report two measurements: i) 𝜙 meson nuclear modification using the muon spectrometer in d + Au, Cu + Au and Au + Au which can explore how strangeness are affected by initial and final state effects and its behavior in QGP at large rapidity; ii) $\pi^{0}$ nuclear modification factor in d + Au collisions which are sensitive to parton shadowing and gluon saturation.
