    • Dipole rescattering and the nuclear structure function 

      Carvalho, F. [UNIFESP]; Goncalves, V. P. B.; Navarra, F. S.; Oliveira, E. G.; Goncalves, V. P.; DaSilva, MLL; Amaral, JTD; Machado, MVT (Amer Inst Physics, 2013-01-01)
      In the framework of the dipole model, we study the effects of the dipole multiple scatterings in a nuclear target and compute the nuclear structure function. We compare different unitarization schemes and confront our ...
    • The energy dependence of leading neutron spectra 

      Carvalho, F. [UNIFESP]; Goncalves, V. P.; Navarra, F. S.; Spiering, D. (Elsevier science bv, 2016)
      We use the color dipole formalism to study e + p -> e + n + X collisions at high energies and calculate the Feynman momentum (x(L)) distribution of leading neutrons, which is expressed in terms of the pion flux and the ...
    • Exclusive vector meson photoproduction with a leading baryon in photon-hadron interactions at hadronic colliders 

      Carvalho, F. [UNIFESP]; Goncalves, V. P.; Navarra, F. S.; Spiering, D. (Amer Physical Soc, 2018)
      Exclusive vector meson photoproduction associated with a leading baryon (B = n, Delta(+), Delta(0)) in pp and pA collisions at RHIC and LHC energies is investigated using the color dipole formalism and taking into account ...
    • Leading neutron production at hera in the color dipole approach 

      Carvalho, F. [UNIFESP]; Goncalves, V. P.; Spiering, D.; Navarra, F. S. (E d p sciences, 2016)
      In this work we study leading neutron production in e + p -> e + n + X collisions at high energies and calculate the Feynman xL distribution of these neutrons. The differential cross section is written in terms of the pion ...
    • A MAG-Landau interpolating gauge for Yang-Mills theory on the lattice 

      Mihara, Antonio; Goncalves, V. P.; DaSilva, MLL; Amaral, JTD; Machado, MVT (Amer Inst Physics, 2013-01-01)
      In this work it is presented a functional for the fixing of a gauge that interpolates between the maximally Abelian gauge (MAG) and Landau gauge, for the case of SU(2) lattice gauge theory. the continuum limit of its ...
    • Non-linear QCD dynamics in two-photon interactions at high energies 

      Carvalho, F. [UNIFESP]; Navarra, F. S.; Goncalves, V. P. B.; Cazaroto, E.; Goncalves, V. P.; DaSilva, MLL; Amaral, JTD; Machado, MVT (Amer Inst Physics, 2013-01-01)
      Assuming that the diploe - dipole cross section can be related with the dipole - proton cross section, we calculate the total gamma gamma, gamma*gamma* cross-sections and the real photon structure function F-2(gamma)(x,Q(2)) ...
    • Non-linear QCD dynamics in two-photon interactions at high energies 

      Goncalves, V. P.; Kugeratski, M. S.; Cazaroto, E. R.; Carvalho, F. [UNIFESP]; Navarra, F. S. (Springer, 2011-10-01)
      Perturbative QCD predicts that the growth of the gluon density at high energies should saturate, forming a Color Glass Condensate (CGC), which is described in mean field approximation by the Balitsky-Kovchegov (BK) equation. ...
    • Nuclear shadowing in deep-inelastic scattering on nuclei: Comparing predictions of three unitarization schemes 

      Carvalho, F. [UNIFESP]; Goncalves, V. P.; Navarra, F. S.; Oliveira, E. G. de (Amer Physical Soc, 2013-06-20)
      The measurement of the nuclear structure functions F-2(A) (x, Q(2)) and F-L(A) (x, Q(2)) at the future electron-ion collider will be of great relevance to understanding the origin of nuclear shadowing and to probe gluon ...
    • Tetraquark production in double parton scattering 

      Carvalho, F. [UNIFESP]; Cazaroto, E. R.; Goncalves, V. P.; Navarra, F. S. (Amer Physical Soc, 2016)
      We develop a model to study tetraquark production in hadronic collisions. We focus on double parton scattering and formulate a version of the color evaporation model for the production of the X(3872) and of the T-4c ...
    • Tetraquark production in hadronic collisions 

      Carvalho, F. [UNIFESP]; Cazaroto, E. R.; Goncalves, V. P.; Navarra, F. S. (Karger, 2016)
      We develop a formalism to study the tetraquark production in hadronic collisions. We focus on double parton scattering and formulate a version of the color evaporation model for the production of the T-4c tetraquark, a ...
