The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date. en_US dc.language.iso eng en_US dc.publisher Springer Verlag en_US dc.relation.ispartof Journal of High Energy Physics (JHEP) en_US dc.relation.isversionof 10.1007/JHEP11(2021)153 en_US dc.rights info:eu-repo/semantics/openAccess en_US dc.subject Beyond Standard Model en_US dc.subject Dark matter en_US dc.subject Hadron-Hadron scattering (experiments) en_US dc.subject Higgs physics en_US dc.title Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV en_US dc.type article en_US dc.authorid 0000-0002-0103-1488 en_US dc.department Mühendislik Fakültesi, Elektrik-Elektronik Mühendisliği Bölümü en_US dc.contributor.institutionauthor Özdemir, Kadri dc.identifier.issue 11 en_US dc.identifier.startpage 1 en_US dc.identifier.endpage 72 en_US dc.relation.publicationcategory Makale - Uluslararası Hakemli Dergi - Kurum Öğretim Elemanı en_US
