"Figure 14b" of "Nuclear-Modification Factor for Open-Heavy-Flavor Production at Forward Rapidity in Cu+Cu Collisions at sqrt(s_NN)=200 GeV"

Comparison of $R_{AA}$ as a function of $N_{part}$ between heavy-flavor muons reconstructed at forward rapidity ($1.4$ 2 GeV in Cu+Cu collisions (red squares) and nonphotonic electrons reconstructed at midrapidity and $p_T>$ 3 GeV in Au+Au collisions (blue circles).
