D$_{s}$ Meson Reconstruction from STAR Heavy Flavor Tracker

Nucleus-Nucleus Collisions at RHIC (the Relativistic Heavy Ion Collider) have produced a strongly interacting dense partonic matter whose degrees of freedom are governed by the Quantum ChromoDynamics (QCD). The Solenoid Tracker At RHIC (STAR) is an ongoing major experiment which aims to study the properties of the QCD matter under extreme energy density, pressure, and temperature. Heavy quark production and propagation are unique probes to the dense matter created at RHIC. The HFT (Heavy Flavor Tracker) is a proposed detector upgrade of STAR, capable of reconstructing open charm hadrons from hadronic decay channels. We carry out a study of D$_{s}$ meson reconstruction using GEANT simulations. We reconstruct D$_{s}$ mesons through a 3-body decay of K$^{+}$K$^{-}\pi $ at displaced vertices as a function of transverse momentum. We present preliminary results on the statistical significance of the reconstructed D$_{s}$ signal as well as on the D$_{s}$ detection efficiency using HFT. The physics impact of the D$_{s}$ measurement will also be discussed.
