Experimental results at RHIC and at the LHC show the same strong suppression for
light and heavy quark probes at high $p_T$, and a possible quark mass
dependence at low $p_T$. More high precision measurements of separated charm and bottom are needed to quantify the dependence of medium energy loss on the quark mass.
The PHENIX Experiment measures electrons from heavy flavor decays using displaced
vertex distributions at mid-rapidity $|y|<$0.35. The nuclear modification of
charm and bottom decays in the semi-electronic channel is obtained for
$1 < p_T < 8$ GeV/c from the new 2015 $p$+$p$ reference data and a much-improved analysis of the 2014 high statistics Au+Au data. PHENIX is also able to measure $B\rightarrow $J$/\psi$ decays in the rapidity range $1.2<|y|<2.2$ for $p_T>0$.
This presentation will report on the nuclear modification factor of separated
charm and bottom yields at mid-rapidity along with the status of the forward rapidity $B\rightarrow$J/$\psi$ analysis using the large statistics obtained during the 2014 Au+Au run.
