Performance of CMS muon reconstruction from proton-proton to heavy ion collisions
(2024) [Artigo de periódico]The performance of muon tracking, identification, triggering, momentum resolution, and momentum scale has been studied with the CMS detector at the LHC using data collected at √ 𝑠NN = 5.02 TeV in proton-proton (pp) and ... -
Search for long-lived particles decaying in the CMS muon detectors in proton-proton collisions at √𝑠 =13 TeV
(2024) [Artigo de periódico]A search for long-lived particles (LLPs) decaying in the CMS muon detectors is presented. A data sample of proton-proton collisions at √𝑠 =13 TeV corresponding to an integrated luminosity of 138 fb−1, recorded at the ... -
Produção de elementos químicos no universo
(2025) [Artigo de periódico]Os elementos químicos da Tabela Periódica (TP), constituídos por partículas fundamentais, formam a matéria luminosa (matéria bariônica), ou seja, a matéria prima de tudo o que conseguimos medir e observar no Universo, que ... -
Rapidity dependence of antideuteron coalescence in pp collisions at √𝑠 = 13 TeV with ALICE
(2025) [Artigo de periódico]The √ production yields of antideuterons and antiprotons are measured in pp collisions at a center-of-mass energy of 𝑠 = 13 TeV, as a function of transverse momentum (𝑝T) and rapidity (𝑦), for the first time ... -
Search for bottom-type vectorlike quark pair production in dileptonic and fully hadronic final states in proton-proton collisions at √𝑠 = 13 TeV
(2024) [Artigo de periódico]A search is described for the production of a pair of bottom-type vectorlike quarks (B VLQs) with mass greater than 1000 GeV. Each B VLQ decays into a b quark and a Higgs boson, a b quark and a Z boson, or a t quark and a ... -
Measurement of the production cross section for a W boson in association with a charm quark in proton–proton collisions at √s = 13 TeV
(2024) [Artigo de periódico]The strange quark content of the proton is probed through the measurement of the production cross section for a W boson and a charm (c) quark in proton–proton collisions at a center-of-mass energy of 13 TeV. The analysis ... -
Performance of the CMS high-level trigger during LHC Run 2
(2024) [Artigo de periódico]The CERN LHC provided proton and heavy ion collisions during its Run 2 operation period from 2015 to 2018. Proton-proton collisions reached a peak instantaneous luminosity of 2.1 × 1034 cm −2 s −1 , twice the initial design ... -
Searches for violation of Lorentz invariance in top quark pair production using dilepton events in 13 TeV proton-proton collisions
(2024) [Artigo de periódico]A search for violation of Lorentz invariance in the production of top quark pairs (tt) is presented. The measured normalized differential tt production cross section, as a function of the sidereal time, is examined for ... -
Provinciality of ostracoda (crustacea) in the northeastern and eastern brazilian shelves based on neontological and paleontological analyses
(2022) [Artigo de periódico]This study analyzes the geographical distribution of 131 podocopid ostracod species recovered from the Brazilian continental shelf between Cabo de São Roque (lat. 05°30’S) and Cabo Frio (lat. 23oS). This very large area ... -
