    • Analysis of the photoproduction of massive gauge bosons at the LHeC 

      Mariotto, Cristiano Brenner; Machado, Magno Valério Trindade (2012) [Artigo de periódico]
      In this work we investigate the photoproduction of massive gauge bosons, W± and Zº, as part of relevant physics topics to be studied in the proposed electron-proton collider, the Deep Inelastic Electron- Nucleon Scattering ...

    • Matter-antimatter asymmetry and non-inertial effects 

      Silveira, Vinicius Medeiros Gomes da; Vasconcellos, Cesar Augusto Zen; Luna, Emerson Gustavo de Souza; Hadjimichef, Dimiter (2021) [Artigo de periódico]
      We investigate non-inertial effects on CP-violating processes using a model, based on the framework of quantum field theory in curved spacetimes, devised to account for the decay of accelerated particles. We show that the ...

    • Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at √s = 13 TeV 

      Sirunyan, A. M.; Silveira, Gustavo Gil da; CMS Collaboration (2018) [Artigo de periódico]
      A search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at ffiffiffi s p ¼ 13 TeV. The data sample was collected in 2016 with the CMS ...

    • The 7% rule : a maximum entropy prediction on new decays of the Higgs boson 

      Alves, Alexandre; Dias, Alex Gomes; Silva, Roberto da (2020) [Artigo de periódico]
      The entropy of the Higgs boson decay probabilities distribution in the Standard Model (SM) is maximized for a Higgs mass value that is less than one standard deviation away from the current experimental measurement. This ...
