Abstract
This paper describes the AC-coupled, single-sided, p-in-n silicon microstrip sensors used in the Semiconductor Tracker (SCT) of the ATLAS experiment at the CERN Large Hadron Collider (LHC) The sensor requirements, specifications and designs are discussed, together with the qualification and quality assurance procedures adopted for their production The measured sensor performance is presented, both initially and after irradiation to the fluence anticipated after 10 years of LHC operation The sensors are now successfully assembled within the detecting modules of the SCT, and the SCT tracker is completed and integrated within the ATLAS Inner Detector Hamamatsu Photonics Ltd supplied 922percent of the 15,392 installed sensors, with the remainder supplied by CiS

A Search for Nothing: Dark Matter and Invisible Decays of the Higgs Boson at the ATLAS Detector

TL;DR: In this article, the invisible branching ratio of the Higgs boson was investigated using the vector boson fusion channel and the results were interpreted using a modified frequentist method and were found to be consistent with the Standard Model expectations.

Upgrading the ATLAS barrel tracker for the super-LHC

TL;DR: In this paper, an all-silicon tracker is designed to cope with the order of magnitude increase in pile-up backgrounds at the higher luminosity. But the tracker is not suitable for high-luminosity operation due to radiation damage and event density.
