    • Nonperturbative gluon exchange in pp elastic scattering at TeV energies 

      Bopsin, Gustavo Barbosa; Luna, Emerson Gustavo de Souza; Natale, Adriano Antonio; Peláez, Marcela (2023) [Artigo de periódico]
      We investigate the two-gluon-exchange model of the Pomeron using nonperturbative gluon propagators characterized by a dynamical mass scale. We present the results for an analysis of the available p p differential cross ...

    • QCD effective charges and the structure function F2 at small-x : higher twist effects 

      Hadjimichef, Dimiter; Luna, Emerson Gustavo de Souza; Peláez, Marcela (2020) [Artigo de periódico]
      We consider the effect of higher twist operators of the Wilson operator product expansion in the structure function F2(x, Q 2) at small-x, taking into account QCD effective charges whose infrared behavior is constrained ...

    • 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 ...
