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 ttH 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 ttH production and H bb decays. 001434518 588__ $$aOnline resource; title from PDF title page (SpringerLink, viewed March 30, 2021). 001434518 650_0 $$aHiggs bosons. 001434518 650_0 $$aQuarks. 001434518 650_0 $$aCollisions (Nuclear physics) 001434518 650_0 $$aRadioactive decay. 001434518 650_6 $$aBosons de Higgs. 001434518 650_6 $$aQuarks. 001434518 650_6 $$aCollisions (Physique nucléaire) 001434518 650_6 $$aDécroissance radioactive. 001434518 655_0 $$aElectronic books. 001434518 77608 $$iPrint version:$$z303065379X$$z9783030653798$$w(OCoLC)1206236280 001434518 830_0 $$aSpringer theses. 001434518 852__ $$bebk 001434518 85640 $$3Springer Nature$$uhttps://univsouthin.idm.oclc.org/login?url=https://link.springer.com/10.1007/978-3-030-65380-4$$zOnline Access$$91397441.1 001434518 909CO $$ooai:library.usi.edu:1434518$$pGLOBAL_SET 001434518 980__ $$aBIB 001434518 980__ $$aEBOOK 001434518 982__ $$aEbook 001434518 983__ $$aOnline 001434518 994__ $$a92$$bISE
