Higgs. 48 years later, in 2012, the so-called Higgs boson was discovered in proton-proton collisions recorded by experiments at the LHC. Since then, its ability to interact with quarks remained experimentally unconfirmed...This book presents a search for Higgs bosons produced in association with top quarks?.tt?H.?in data recorded with the CMS detector in 2016. It focuses on Higgs boson decays into bottom quarks?H →?bb??and top quark pair decays involving at least one lepton. In this analysis, a multiclass classification approach using deep learning techniques was applied for the first time. In light of the dominant background contribution from?.tt?.?production, the developed method proved to achieve superior sensitivity with respect to existing techniques. In combination with searches in different decay channels, the presented work contributed to the first observations of?.tt?H.?.production and H?→?bb??decays.. | | 出版日期 | Book 2021 | | 關(guān)鍵詞 | Higgs Boson Production; Tth Production; Bb Channel; Tth Search; Tthbb Search; CMS Experiment; Machine Lear | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-65380-4 | | isbn_softcover | 978-3-030-65382-8 | | isbn_ebook | 978-3-030-65380-4Series 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 |
