Charm production and hadronization processes are believed to be important probes for novel phenomena in heavy ion collision at the Relativistic Heavy Ion Collider (RHIC). Charm production can be studied via semi-leptonic decays of D mesons into muons as measured in the PHENIX experiment muon detectors. There is a significant background contribution to single muons from pion and kaon decay. Pions and kaons typically are absorbed in material before the muon spectrometer; however, some will decay to muons first. The probability that they decay and the resulting muon is accepted in the PHENIX muon detector has a strong collision vertex dependence, unlike the muons from charm. This could provide a method to separate the contribution of muons from pions and kaons from the D meson contribution. In this talk, we will present simulation studies of the single muon contributions and also preliminary Run 2 data analysis results.
