Time Projection

The combination of the ionization energy loss (dE/dx) from Time Projection Chamber (TPC) at ≃ 8% resolution and multi-gap resistive plate chamber time-of-flight (TOF) at 85ps provides powerful particle identification. We present spectra of identified charged pions from transverse momentum pT≃0.2 GeV/c to 7-8 GeV/c in Au + Au collisions at [Formula: see text]. Physics implications will be discussed.

Cms Detector

The large sensitive volume of the Silicon Strip Tracker of CMS detector allows, for a typical track, up to 20 samplings of the specific energy loss by ionization, providing a powerful tool for particle identification at low βγ values. We report on the application to hadron identification in the first pp collisions recorded by the CMS detector at [Formula: see text] and 7 TeV and on applications to other CMS analyses, including the search for highly-ionizing exotic particles.

Dielectron signal reconstruction is an important tool for heavy flavor measurements because of its trigger feasibility and its relatively straightforward particle identification process. However, in the case of time projection chamber detectors, some hadron contamination is unavoidable, even if additional means are used to improve the particle identification process. In this paper, we investigate the effects of hadron (protons, pions, and kaons) contamination on the dielectron signal reconstruction process in the measurement ofJ/ψand electrons from heavy flavor hadron decays.
