    • Excitation rates of heavy quarks 

      Canal, Carlos Alberto Garcia; Santangelo, Eve Mariel; Gay Ducati, Maria Beatriz (1985) [Artigo de periódico]
      We obtain the production rates for c, b, and t quarks in deep-inelastic neutrino- (antineutrino-) nucleon interactions, in the standard six-quark model with left-handed couplings. ,The results are obtained with the most ...

    • Nuclear charm and bottom production : a comparison among high energy approaches 

      Goncalves, Victor Paulo Barros; Machado, Magno Valério Trindade (2004) [Artigo de periódico]
      We calculate the nucleon and nuclear photoproduction cross sections for heavy quarks within the k⊥-factorization formalism, considering the current high energy approaches which include nuclear and saturation effects. Our ...

    • 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. ...
