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. | | 出版日期 | Book 2020 | | 关键词 | ATLAS detector at CERN; Flavour physics; Supersymmetry; Squark; Tagging; Tracking; Vertex | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-54288-7 | | isbn_softcover | 978-3-030-54290-0 | | isbn_ebook | 978-3-030-54288-7Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerl |
