Title Searching for Squarks : in Compressed States and States with Jets from Charm Quarks with the Atlas Detector Author(s) Jones, Samuel Publication Cham, Springer International Publishing, 2020. Description XVIII, 223 p. 136 illus., 109 illus. in color : online resource Abstract Note This thesis focuses on searches for squarks with the ATLAS detector in "compressed" scenarios where the scalar top is very close in mass to the lightest supersymmetric particle. These models are theoretically appealing because the presence of a quasi-degenerate scalar top enhances the self-annihilation cross-section of the lightest supersymmetric particle, acting therefore as a regulator of the dark matter relic density. Two main analyses are presented: the first is a search for scalar tops decaying to charm quarks. The identification of jets originating from the charm quark is very challenging due to its short lifetime. The calibration of tools for charm-tagging has paved the way to measuring the decay of the Higgs boson to pairs of charm quarks. The second analysis presented is the development of a novel technique for reconstructing low momentum b-hadrons. This tool has enabled the ATLAS collaboration to explore topologies that were previously inaccessible ISBN,Price 9783030542887 Keyword(s) 1. EBOOK 2. EBOOK - SPRINGER 3.
