| الوصف: | Particle identification (PID) capabilities are studied by using the Time Projection Chamber (TPC) and a Time-Of-Flight (TOF) detector together at STAR. The identification capability of charged hadrons is greatly extended compared with that achieved by TPC and TOF separately. Particle spectra from p+p, d+Au collisions at √ s NN =200 GeV and Au+Au collisions at √ s NN =62.4 GeV are used to develop the methods. The transverse momentum (pT) ranges of π, and p(¯p) identification are from ∼ 0.3 GeV/c to ∼ 10 GeV/c. The high pT reach is limited by statistics in current data sets. An important conceptual advance was developed to identify electrons by using a combination of dE/dx in TPC and velocity information from the TOF detectors, which is important for future low-mass dilepton program at STAR. |
