The PHENIX Collaboration at the Relativistic Heavy Ion Collider has measured open heavy flavor production in minimum bias Au+Au collisions at √ s N N = 200 GeV via the yields of electrons from semileptonic decays of charm and bottom hadrons. Previous heavy flavor electron measurements indicated substantial modification in the momentum distribution of the parent heavy quarks due to the quark-gluon plasma created in these collisions. For the first time, using the PHENIX silicon vertex detector to measure precision displaced tracking, the relative contributions from charm and bottom hadrons to these electrons as a function of transverse momentum are measured in Au+Au collisions. We compare the fraction of electrons from bottom hadrons to previously published results extracted from electron-hadron correlations in p+p collisions at √ s N N = 200 GeV and find the fractions to be similar within the large uncertainties on both measurements for pT > 4 GeV/c. We use the bottom electron fractions in Au+Au and p+p along with the previously measured heavy flavor electron RAA to calculate the RAA for electrons from charm and bottom hadron decays separately. We find that electrons from bottom hadron decays are less suppressed than those from charm for the region 3 < pT < 4 GeV/c.

Abstract. The PHENIX experiment at RHIC should be sensitive to decays of the the anti-pentaquark Θ − via the K − n channel. Charged kaons can be identified using the standard tracking and time of flight up to a momentum of 1.5 GeV/c. Antineutron candidates are detected via their annihilation signal in the highly segmented electromagnetic calorimeter (EMCal). In order to assess the quality of the anti-neutron identification we reconstruct the Σ → nπ. As an additional crosscheck the invariant mass of K + n is reconstructed where no resonance in the pentaquark mass range is expected. At the present time no enhancement at the expected pentaquark mass is observed in dAu collisions at √ s N N = 200 GeV.The possibility of five quark systems (pentaquarks) has been discussed for more than two decades (see, e.g. Ref The reconstruction of the Θ + pentaquark is technically difficult in PHENIX [12], due to the relatively small acceptance for 3-body final states and the difficulty of detecting neutrons. However, due to the unique signature of anti-neutrons in the highly segmented PHENIX electromagnetic calorimeter, a search for decays of the antipentaquark Θ − → K − n is technically feasible.Charged particles are tracked using the central arm spectrometers [13]. The kaon identification is accomplished by combining their momentum obtained from the tracking detectors with their time-of-flight as measured by the EMCal, shown in fig. 1. The upper limit of the momenta for separating kaons is 1.5 GeV/c, beyond which the contamination by pions becomes too large.The anti-neutron candidates are selected via their annihilation signal in the EMCal. Since there is no independent measurement of anti-neutrons to calibrate the EMCal response, guidance for identifying the anti-neutron signal is provided § For the full PHENIX Collaboration author list and acknowledgments , see Appendix "Collaborations" of this volume.

ϕ Meson Production at Forward Rapidity with the PHENIX Detector at RHIC

Abstract. The φ meson production in p+p collisions is an important tool to study QCD, providing data to tune phenomenological QCD models, while in high-energy heavy-ion collisions it provides key information on the hot and dense state of the strongly interacting matter produced in such collisions. It is sensitive to the medium-induced effects such as strangeness enhancement, a phenomenon associated with soft particles in bulk matter. Measurements in the dilepton channels are especially interesting since leptons interact only electromagnetically, thus carrying the information from their production phase directly to the detector. Measurements in different nucleus-nucleus collisions allow us to perform a systematic study of the nuclear medium effects on φ meson production. The PHENIX detector provides the capabilities to measure the φ meson production in a wide range of transverse momentum and rapidity to study various cold nuclear effects such as soft multiple parton rescattering and modification of the parton distribution functions in nuclei. In this proceeding, we report the most recent PHENIX results on φ meson production in p+p, d+Au and Cu+Au collisions.
