    • Asymptotic gluon density within the color dipole picture in light of HERA high-precision data 

      Fagundes, Daniel Almeida; Machado, Magno Valério Trindade (2023) [Artigo de periódico]
      We present an analysis of the most precise set of Hadron-Electron Ring Accelerator (HERA) data within the color dipole formalism, by using an analytical gluon density, based on the double-logarithm approximation of the ...

    • Forward elastic scattering : dynamical gluon mass and semihard interactions 

      Rocha, Mateus Broilo da; Fagundes, Daniel Almeida; Luna, Emerson Gustavo de Souza; Menon, Marcio Jose (2019) [Artigo de periódico]
      The role of low-x parton dynamics in dictating the high-energy behavior of forward scattering observables at LHC energies is investigated using a QCD-based model with even-under-crossing amplitude dominance at high-energies. ...

    • Proton-proton forward scattering at the LHC 

      Rocha, Mateus Broilo da; Fagundes, Daniel Almeida; Luna, Emerson Gustavo de Souza; Menon, Marcio Jose (2019) [Artigo de periódico]
      Recently the TOTEM experiment at the LHC has released measurements at √s=13 TeV of the proton-proton total cross section, σtot, and the ratio of the real to imaginary parts of the forward elastic amplitude, ρ. Since then ...

    • QCD traveling waves phenomenology revisited 

      Amaral, João Thiago de Santana; Fagundes, Daniel Almeida; Machado, Magno Valério Trindade (2021) [Artigo de periódico]
      In this paper, we review and update the Amaral-Gay Ducati-Betemps-Soyez saturation model, by testing it against the recent H1-ZEUS combined data on deep inelastic scattering, including heavy quarks in the dipole amplitude. ...

    • Soft diffraction within the QCD color dipole picture 

      Peccini, Guilherme Müller; Nóbrega, Fábio Köpp; Machado, Magno Valério Trindade; Fagundes, Daniel Almeida (2020) [Artigo de periódico]
      In this work we consider the QCD parton saturation models to describe soft interactions at the high energy limit. The total and elastic cross sections, as well as the elastic slope parameter, are obtained for proton-proton ...

    • Soft pomeron in light of the LHC correlated data 

      Rocha, Mateus Broilo da; Fagundes, Daniel Almeida; Luna, Emerson Gustavo de Souza; Peláez, Marcela (2021) [Artigo de periódico]
      The LHC has released precise measurements of elastic proton-proton scattering that provide a unique constraint on the asymptotic behavior of the scattering amplitude at high energies. Recent reanalyses of part of these ...
