Analysis Status of The Measurement of Charm and Bottom Production in PHENIX

It has long been observed experimentally, from previous heavy-flavor electron measurements, that heavy quarks are subject to substantial modifications of their momentum spectrum. The PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC) has measured open heavy-flavor production in minimum bias p+p and Au+Au collisions at $\sqrt[]{S_{NN}}$ = 200 GeV, by measuring the different decay lengths using a silicon vertex detector. The comparisons between Au+Au and p+p collisions shed light on properties of hot nuclear matter, as well as quark-gluon plasma's influence on the heavy-flavor electron's nuclear modification factor $R_{AA}$. In our analysis, p+Au collisions at $\sqrt[]{S_{NN}}$ = 200 GeV are studied, and provide another contributing factor to heavy-ion collision as the cold nuclear matter baseline. The status of the analysis will be presented including data quality assurance, recalibration and electron identification, production of inclusive electrons' DCA distribution measured by VTX, as well as simulation of the DCA distributions of electron backgrounds.
