Electrons and Heavy Quark at PHENIX Detector
Measurement of heavy quark production is one of the tools used to investigate the matter produced in extremely hot and dense conditions in heavy ion collisions at RHIC. The PHENIX experiment has measured mid-rapidity transverse momentum spectra of electrons. After subtracting the photonic background contribution, the electron spectra are mainly due to semileptonic decays of hadrons containing h...
متن کاملElliptic Flow Measurements with the PHENIX Detector
Two particle azimuthal correlation functions are presented for charged hadrons produced in Au + Au collisions at RHIC ( √ s NN = 130 GeV). The measurements allow for the determination of elliptic flow without event-by-event estimation of the reaction plane. The measured correlation functions indicate elliptic flow values (v2) which show significant sensitivity to both the collision centrality a...
متن کاملφ- meson Production at RHIC energies using the PHENIX Detector
Light vector mesons are among the most informative probes to understand the strongly coupled Quark Gluon Plasma created at RHIC. The suppression of light mesons at high transverse momentum, compared to expectations from scaled p + p results, reflects the properties of the strongly interacting matter formed. The φ-meson is one of the probes whose systematic measurement in p + p, d + Au and Au + ...
متن کاملHigh pT Direct Photon-Hadron Correlations Using the PHENIX Detector
Jet tomography, the study of differential energy loss of hard scattered partons to infer the density profile of the medium, is greatly improved by precise knowledge of the initial energy of the hard probe. As photons are not strongly interacting, the momentum of the recoil jet from a direct photon trigger is balanced, to a good approximation, by the momentum of the photon. The energy loss of th...
متن کاملProposal for a Hadron Blind Detector for PHENIX
A Hadron Blind Detector (HBD) is proposed as upgrade of the PHENIX detector at RHIC, BNL. The HBD will allow the measurement of low-mass ee pairs from the decay of the light vector mesons ρ, ω, φ and the low-mass continuum in Au-Au collisions at energies up to √ sNN= 200 GeV . From MC simulations and general considerations, the HBD has to identify electrons with very high efficiency (> 90%), do...
