“…The ID is the nearest to the interaction region, and it is used to reconstruct charged particle tracks for the selection of physics objects in nearly all trigger signatures. The ID sub-components are High-granularity Silicon detectors -Pixel [3] and microstrip (SCT) [4] and a straw tube Transition Radiation Tracker (TRT) [5]. The innermost pixel layer, the insertable B-layer (IBL) [6], was added for the start of Run 2 to allow a more robust track reconstruction, with better impact parameter resolution and more precise vertex reconstruction.…”

Performance of the ATLAS Transition Radiation Tracker in Run 1 of the LHC: tracker propertiesThe ATLAS CollaborationThe tracking performance parameters of the ATLAS Transition Radiation Tracker (TRT) as part of the ATLAS inner detector are described in this paper for different data-taking conditions in proton-proton, proton-lead and lead-lead collisions at the Large Hadron Collider (LHC). The performance is studied using data collected during the first period of LHC operation (Run 1) and is compared with Monte Carlo simulations. The performance of the TRT, operating with two different gas mixtures (xenon-based and argon-based) and its dependence on the TRT occupancy is presented. These studies show that the tracking performance of the TRT is similar for the two gas mixtures and that a significant contribution to the particle momentum resolution is made by the TRT up to high particle densities.

Search for Charginos Nearly Mass-Degenerate with the Lightest Neutralino

A search is presented for direct chargino production based on a disappearing-track signature using 20.3 fb −1 of proton-proton collisions at √ s = 8 TeV collected with the ATLAS experiment at the Large Hadron Collider. In anomaly-mediated supersymmetry breaking (AMSB) models, the lightest chargino is nearly massdegenerate with the lightest neutralino and its lifetime is long enough to be detected in the tracking detectors by identifying decays that result in tracks with no associated hits in the outer region of the tracking system. Other supersymmetric models with the pure neutral wino being the lightest supersymmetric particle also predict the same signature. This analysis attains sensitivity for charginos with a lifetime between 0.1 and 10 ns, and significantly surpasses the reach of the LEP experiments due to an enhanced track reconstruction efficiency for charginos having short decay length and a dedicated topological trigger to attain a higher signal efficiency. No significant excess above the background expectation is observed for candidate tracks with large transverse momentum, and constraints on chargino properties are obtained. In the AMSB scenarios, a chargino mass below 270 GeV is excluded at 95% confidence level, which also directly constrains the mass of wino dark matter.
