Weak transition form factors of heavy-light pseudoscalar mesons for space- and timelike momentum transfers
Oliver Heger, María Gómez-Rocha, Wolfgang Schweiger
Weak and transition form factors are described in both the space- and time-like momentum transfer regions, within a constituen…
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…
Global Dyson-Schwinger-Bethe-Salpeter Approach to Mesons with Open Flavour
Thomas Hilger, María Gómez-Rocha, Andreas Krassnigg +1
Exploiting an interplay of the Bethe-Salpeter equation enabling us to regard mesons as bound states of quark and antiquark and the Dyson-Schwinger equation controlling the dressed…
Effective-particle approach to bound states of quarks and gluons in QCD
María Gómez-Rocha, Kamil Serafin
A general approach to the construction of bound states in quantum field theory, called the renormalization group procedure for effective particles (RGPEP), was applied recently to…
Renormalized quark-antiquark Hamiltonian induced by a gluon mass ansatz in heavy-flavor QCD
Stanisław D. Głazek, María Gómez-Rocha, Jai More +1
In response to the growing need for theoretical tools that can be used in QCD to describe and understand the dynamics of gluons in hadrons in the Minkowski space-time, the renormal…
Asymptotic freedom in the Hamiltonian approach to binding of color
María Gómez-Rocha
We derive asymptotic freedom and the Yang-Mills -function using the renormalization group procedure for effective particles. In this procedure, the concept of effective…
Asymptotic freedom of gluons in the Fock space
Stanisław D. Głazek, Maria Gómez-Rocha
Asymptotic freedom of gluons is described in terms of a family of scale-dependent renormalized Hamiltonian operators acting in the Fock space. The Hamiltonians are obtained by appl…

In this thesis a general relativistic framework for the calculation of the electroweak structure of mesons of arbitrary constituent-quark masses is presented. The physical processe…

We present a relativistic point-form approach for the calculation of electroweak form factors of few-body bound states. As an example, the transition form factors for the semilepto…
