Quarkonia RdAu and FVTX c/b measurement at the PHENIX

Since quarkonia are produced dominantly by gluon-gluon fusion process, it is a good channel to explore the gluon distribution of the nucleon and its modification in nuclei. Contrasting with heavy ion collisions, d + A collisions are not expected to create a hot medium of nuclear matter. Therefore, we can study the quarkonia production in d + A collision and separate the cold nuclear matter effects from the pattern seen in the collisions of large nuclei. The PHENIX collaboration has measured interesting results for J/ψ, ψ' and χc at mid rapidity, |η| < 0.35, and J/ψ and Υ at forward rapidity, 1.2 < η < 2.2 for √SNN = 200 GeV d + Au collisions [1–4]. Recently the Forward Silicon Vertex Detector (FVTX) has been installed to the PHENIX detector and much more precise open heavy flavor and vector meson measurements will be possible in the forward rapidity region of the PHENIX Muon Arms. In this talk we will show the aforementioned quarkonia measurements from PHENIX and report on the status of the FVTX detector and physics analyses that will use the FVTX detector in conjunction with the Muon Arms
