Search for decays of stopped exotic long-lived particles produced in proton-proton collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2018-05)
A search is presented for the decays of heavy exotic long-lived particles (LLPs) that are produced in proton-proton collisions at a center-of-mass energy of 13 TeV at the CERN LHC and come to rest in the CMS detector. Their ...
Identification of heavy-flavour jets with the CMS detector in pp collisions at 13 TeV
(IOP Publishing, 2018-05)
Many measurements and searches for physics beyond the standard model at the LHC rely on the efficient identification of heavy-flavour jets, i.e. jets originating from bottom or charm quarks. In this paper, the discriminating ...
Observation of t[¯ over t] H Production
(American Physical Society, 2018-06)
The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of √s=7, 8, and 13 TeV, corresponding ...
Search for natural and split supersymmetry in proton-proton collisions at √s = 13 TeV in final states with jets and missing transverse momentum
(Springer Berlin Heidelberg, 2018-05)
A search for supersymmetry (SUSY) is performed in final states comprising one or more jets and missing transverse momentum using data from proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded ...
Evidence for exclusive γγ → W⁺ W⁻ production and constraints on anomalous quartic gauge couplings in pp collisions at √s = 7 and 8 TeV
(Springer Nature, 2018-06-13)
A search for exclusive or quasi-exclusive γγ → W⁺W⁻ production, via pp → p (*) W⁺W⁻p (*) → p (*) μ ± e ∓ p (*) at √s = 8 TeV, is reported using data corresponding to an integrated luminosity of 19.7 fb⁻¹. Events are selected ...
Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2018-01)
A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at √s = 13 TeV with the CMS detector at the LHC, corresponding to ...
Search for Physics Beyond the Standard Model in Events with High-Momentum Higgs Bosons and Missing Transverse Momentum in Proton-Proton Collisions at 13 TeV
(American Physical Society, 2018-06)
A search for physics beyond the standard model in events with one or more high-momentum Higgs bosons, H, decaying to pairs of b quarks in association with missing transverse momentum is presented. The data, corresponding ...
Search for dark matter in events with energetic, hadronically decaying top quarks and missing transverse momentum at √ s = 13 TeV
(Springer Berlin Heidelberg, 2018-06)
A search for dark matter is conducted in events with large missing transverse momentum and a hadronically decaying, Lorentz-boosted top quark. This study is performed using proton-proton collisions at a center-of-mass ...
Search for Standard Model Production of Four Top Quarks with Same-Sign and Multilepton Final States in Proton–proton Collisions at √s = 13 TeV
(Springer-Verlag, 2018-02)
A search for standard model production of four top quarks (tt¯tt¯) is reported using events containing at least three leptons (e,μ) or a same-sign lepton pair. The events are produced in proton–proton collisions at a ...
Measurement of the Splitting Function in pp and Pb-Pb Collisions at √sNN = 5.02 TeV
(American Physical Society, 2018-04)
Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the ...
