  Forward hadron measurements in p(d)+A provide a signal to study nuclear
shadowing, initial state energy loss and/or gluon saturation effects as a
function of rapidity, centrality and energy. High $p_T$ identified $\pi^{0}$
measurements are an essential first step toward measuring prompt photon
production. The $\pi^{0}$ measurements are enabled by the PHENIX MPC-EX
detector, a Si-W preshower detector located in front of the Muon Piston
Calorimeter (MPC), expanding the neutral pion reconstruction capabilities in
the rapidity range $3.1< \eta <3.8$ out to high energies, $E < 80$ GeV.
Previous PHENIX measurements of punch-through charged hadrons in the muon arms
in the rapidity range $1.4< \vert \eta \vert <2.2$ were significantly improved
through the capability of the forward silicon vertex detector (FVTX) to
determine the transverse momentum and rapidity with high precision and reject
background from secondary hadrons.
  PHENIX collected d+Au data with the MPC-EX in the 2016 run at $\sqrt{s_{NN}}
=$ 200, 62, 39 and 19.6 GeV; and p+p and p+Au(Al) data with the FVTX in 2015 at
200 GeV. In this talk, we will present first results for high $p_T$ $\pi^{0}$
production from the $\sqrt{s_{NN}}$ = 200 GeV dataset, the status of the prompt
photon measurement, as well as charged hadron nuclear modification factors in
p+Au(Al) and $^{3}$He$+$Au.
