Research summary
Several papers document the ATLAS Transition Radiation Tracker (TRT), the outermost tracking subsystem of the ATLAS Inner Detector at the LHC. The TRT barrel detector design, construction and performance are described [1], along with the proportional drift-tube technology that underlies the straw-based TRT [2], the TRT end-cap detectors [4] and the readout electronics [6]. Combined performance tests of the SCT+TRT integration prior to installation are reported in detail [5]. A later study addresses gas-gain stabilization across approximately 350,000 TRT channels, a critical operational requirement for tracking and particle-identification performance in stable LHC running [9]. A LEP-era ALEPH measurement determined the Dalitz-decay branching ratio of the pi0 by comparing pi0 -> e+ e- gamma and pi0 -> gamma gamma rates in roughly four million hadronic Z decays from 1991-1995, yielding B = (1.140 +/- 0.041)% [7]. A separate ALEPH analysis examined residual Bose-Einstein correlations and the Soeding model, treating distortions in mass spectra of non-identical pions in rho decays as a residual effect of correlations among identical pions in the event [8]. Unrelated clinical work established robust haematology reference ranges for healthy adults using the Sysmex XE-2100, CA 1500 and Beckman-Coulter Access analysers, based on 250 healthy laboratory personnel [3].
