### Description

Experimental results from RHIC and LHC show an indication of a mass ordering
on the quark energy loss when crossing the hot and dense medium formed in
A+A collisions. The ordering is more evident at low $p_T$ region, where the
quark mass is more relevant for the energy loss mechanisms. However, this
final-state quark energy loss competes with other effects such as nuclear
shadowing and initial-state energy loss which may also depend on the quark
mass. This presentation is going to show the status of the analysis of charm
and bottom nuclear modification ($R_{AA}$) in the rapidity 1.2$<|y|<$2.2 at
$\sqrt{s_{NN}}$=200 GeV. These  measurements are performed by the PHENIX
forward vertex detectors and muon arms using the $B\rightarrow J/\psi+X$ and
muon decay channels. This rapidity region allows the exploration of
different initial-state effect contributions to the heavy flavor $R_{AA}$.
Besides, the forward measurements have more access to the low-$p_T$ region
because of the additional boost of the non-prompt decay products from heavy
