    • Educação escolar quilombola e o acesso ao ensino superior público brasileiro 

      Nascimento, Matheus Monteiro; Alves-Brito, Alan (2024) [Artigo de periódico]
      No âmbito das discussões sobre educação escolar quilombola diferenciada, a ambiguidade raça-classe se apresenta como um empecilho epistêmico importante. Apesar de algumas décadas de investimento analítico na problematização ...
    • AGN feedback and star formation in the peculiar galaxy NGC 232 : insights from VLT-MUSE observations 

      Souza, José Henrique Costa Pinto; Riffel, Rogemar André; Dors Júnior, Oli Luiz; Riffel, Rogério; Poppe, Paulo César da Rocha (2024) [Artigo de periódico]
      We use VLT-MUSE integral field unit data to study the ionized gas physical properties and kinematics as well as the stellar populations of the Seyfert 2 galaxy NGC 232 as an opportunity to understand the role of AGN feedback ...
    • Observation of four top quark production in proton-proton collisions at √𝑠 = 13TeV 

      Hayrapetyan, Aram; Silveira, Gustavo Gil da; Bernardes, César Augusto; CMS Collaboration (2023) [Artigo de periódico]
      The observation of the production of four top quarks in proton-proton collisions is reported, based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 TeV in 2016–2018 at the CERN LHC and ...
    • Measurement of the tt¯ charge asymmetry in events with highly Lorentz-boosted top quarks in pp collisions at √s = 13 TeV 

      Tumasyan, Armen; Silveira, Gustavo Gil da; Bernardes, César Augusto; CMS Collaboration (2023) [Artigo de periódico]
      The measurement of the charge asymmetry in top quark pair events with highly Lorentz-boosted top quarks decaying to a single lepton and jets is presented. The analysis is performed using proton proton collisions at √s = ...
    • Data-driven precision determination of the material budget in ALICE 

      Acharya, Shreyasi; Gay Ducati, Maria Beatriz; Pereira, Luis Gustavo; ALICE Collaboration (2023) [Artigo de periódico]
      The knowledge of the material budget with a high precision is fundamental for measurements of direct photon production using the photon conversion method due to its direct impact on the total systematic uncertainty. Moreover, ...
    • Tendências atuais sobre o Ensino de Física Moderna : uma revisão de literatura 

      Januário, Maria Derlandia de Araújo; Hoernig, André Felipe; Massoni, Neusa Teresinha (2024) [Artigo de periódico]
      Este artigo é uma revisão de literatura que explora tópicos de Física Moderna (FM) no contexto do Ensino de Física, como parte de um estudo de doutoramento que tem como objetivo introduzir FM no Ensino Médio (EM) com uma ...
    • A search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometer 

      Tumasyan, Armen; Silveira, Gustavo Gil da; Bernardes, César Augusto; CMS Collaboration (2023) [Artigo de periódico]
      A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, pp → pp + Z/γ + X, in proton-tagged events from proton–proton collisions at √s = 13 ...
    • SDSS-IV MaNGA : the role of the environment in AGN triggering 

      Rembold, Sandro Barboza; Riffel, Rogério; Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Schimoia, Jáderson da Silva; Valk, Greique A.; Lorenzoni, Vanessa; Ilha, Gabriele da Silva; Costa, Luiz N. da (2024) [Artigo de periódico]
      The large- and small-scale environments around optically-selected AGN host galaxies and a controlsample of non-active galaxies in the MaNGA survey have been investigated in order to evaluate the importance of the environment ...
    • A consistent view of interacting dark energy from multiple CMB probes 

      Zhai, Yuejia; Giarè, William; Bruck, Carsten van de; Di Valentino, Eleonora; Mena Requejo, Olga; Nunes, Rafael da Costa (2023) [Artigo de periódico]
      We analyze a cosmological model featuring an interaction between dark energy and dark matter in light of the measurements of the Cosmic Microwave Background released by three independent experiments: the most recent data ...
    • Evidence for four-top quark production in proton-proton collisions at √s = 13 TeV 

      Tumasyan, Armen; Silveira, Gustavo Gil da; Bernardes, César Augusto; CMS Collaboration (2023) [Artigo de periódico]
      The production of four top quarks (ttt¯ t)¯ is studied with LHC proton-proton collision data samples collected by the CMS experiment at a center-of-mass energy of 13 TeV, and corresponding to integrated luminosities of up ...
