Description
The Forward Vertex Detector (FVTX) was installed in PHENIX this year
and operated during the $\sqrt{s}=$510 GeV $p$+$p$,
$\sqrt{s_{NN}}=$193 GeV U+U, and $\sqrt{s_{NN}}=$200 GeV Cu+Au
runs. The FVTX has full azimuthal coverage between 1.2$<|y|<$2.2 and
consists of 4 stations with 2 planes of silicon mini-strips with 75 $\mu$m pitch in the
radial direction and 96 azimuthal segments. The resolution of the
distance of closest approach (DCA) measured by the FVTX is suitable for the
identification and separation of charm and bottom quark decay yields. We also
expect to improve the measurement of the dimuon opening angle and
reduce background, providing J/$\psi$, $\psi^{\prime}$ mass peak separation. This poster
will show the status of the analysis of the data collected by the FVTX
this year.
