Renormalization group and scattering-equivalent Hamiltonians on a coarse momentum grid
María Gómez-Rocha, Enrique Ruiz Arriola
We consider the -scattering problem in the context of the Kadyshevsky equation. In this scheme, we introduce a momentum grid and provide an isospectral definition of the phase-…
scattering in a renormalized Hamiltonian matrix
María Gómez-Rocha, Enrique Ruiz Arriola
A Wilsonian approach to scattering based in the Glazek-Wilson Similarity Renormalization Group (SRG) for Hamiltonians is analyzed in momentum space up to a maximal CM energy o…
Isospectral scattering for relativistic equivalent Hamiltonians on a coarse momentum grid
María Gómez-Rocha, Enrique Ruiz Arriola
The scattering phase-shifts are invariant under unitary transformations of the Hamiltonian. However, the numerical solution of the scattering problem that requires to discretize th…
Spectral-shift and scattering-equivalent Hamiltonians on a coarse momentum grid
María Gómez-Rocha, Enrique Ruiz Arriola
The solution of the scattering problem based on the Lippmann-Schwinger equation requires in many cases a discretization of the spectrum in the continuum which does not respect the…
scattering from a similarity renormalization group perspective
María Gómez-Rocha, Enrique Ruiz Arriola
A Wilsonian approach based on the Similarity Renormalization Group to scattering is analyzed in the 00, 11 and 02 channels in momentum space up to a maximal CM energy of…
Open-Flavour Mesons from the Angle of Bethe, Dyson, Salpeter, Schwinger, et al
Thomas Hilger, María Gómez-Rocha, Andreas Krassnigg +1
Recently, we completed a comprehensive investigation of a huge part of the entire meson spectrum by considering both quarkonia and open-flavour mesons by means of a single common f…
