Asymptotic freedom using a gluon mass as a regulator

J. J. Galvez-Viruet, M. Gomez-Rocha

Front-Form Hamiltonian dynamics provides a framework in which QCD's vacuum is simple and states are boost invariant. However, canonical expressions are divergent and must be regula…

Approximate Hamiltonian for baryons in heavy-flavor QCD

Kamil Serafin, María Gómez-Rocha, Jai More +1

Aiming at relativistic description of gluons in hadrons, the renormalization group procedure for effective particles (RGPEP) is applied to baryons in QCD of heavy quarks. The baryo…

Aspects of open-flavour mesons in a comprehensive DSBSE study

T. Hilger, M. Gómez-Rocha, A. Krassnigg +1

Open-flavour meson studies are the necessary completion to any comprehensive investigation of quarkonia. We extend recent studies of quarkonia in the Dyson-Schwinger-Bethe-Salpeter…

From asymptotic freedom toward heavy quarkonia within the renormalization group procedure for effective particles

María Gómez-Rocha

The renormalization group procedure for effective particles (RGPEP), developed as a nonperturbative tool for constructing bound states in quantum field theories, is applied to QCD.…

Leptonic decays of D-wave vector quarkonia

A. Krassnigg, M. Gomez-Rocha, T. Hilger

We give a short and basic introduction to our covariant Dyson-Schwinger-Bethe-Salpeter-equation approach using a rainbow-ladder truncated model of QCD, in which we investigate the…

Effects of a dressed quark-gluon vertex in vector heavy-light mesons and theory average of B(c)* meson mass

M. Gomez-Rocha, T. Hilger, A. Krassnigg

We extend earlier investigations of heavy-light pseudoscalar mesons to the vector case, using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach. We inves…

Asymptocic Freedom of Gluons in Hamiltonian Dynamics

María Gómez-Rocha, Stanisław D. Głazek

We derive asymptotic freedom of gluons in terms of the renormalized Yang-Mills Hamiltonian in the Fock space. Namely, we use the renormalization group procedure for effecti…

Asymptotic freedom in the front-form Hamiltonian for quantum chromodynamics of gluons

Maria Gomez-Rocha, Stanislaw D. Glazek

Asymptotic freedom of gluons in QCD is obtained in the leading terms of their renormalized Hamiltonian in the Fock space, instead of considering virtual Green's functions or scatte…

Masses of J^PC =1^-+ exotic quarkonia in a Bethe-Salpeter-equation approach

T. Hilger, M. Gomez-Rocha, A. Krassnigg

We investigate the properties of mesons with the exotic J^PC = 1^-+ quantum numbers. Starting out from the light-quark domain, where the π_1 states are used as references, we predi…

Semileptonic meson decays in point-form relativistic quantum mechanics: unambiguous extraction of weak form factors

Maria Gomez-Rocha

The point-form version of the Bakamjian-Thomas construction is applied to the description of several semileptonic decays of mesons. Weak form factors are extracted without ambiguit…

Spectra of heavy quarkonia in a Bethe-Salpeter-equation approach

Thomas Hilger, Carina Popovici, Maria Gomez-Rocha +1

In a covariant Bethe-Salpeter-equation approach and with a rainbow-ladder truncated model of QCD, we investigate the use of an effective interaction with the goal of reproducing QC…

On a new approach to meson phenomenology with the Bethe-Salpeter equation

Carina Popovici, Thomas Hilger, Maria Gomez-Rocha +1

We investigate capabilities of the effective interaction in a rainbow-ladder truncated meson model of QCD within a covariant Landau-gauge Bethe-Salpeter-equation approach. Based up…

First look at heavy-light mesons with a dressed quark-gluon vertex

Maria Gomez-Rocha, Thomas Hilger, Andreas Krassnigg

Following up on earlier work, we investigate possible effects of a dressed quark-gluon vertex in heavy-light mesons. In particular, we study corrections to the popular rainbow-ladd…

Form Factors of Few-Body Systems: Point Form Versus Front Form

María Gómez-Rocha, Elmar. P. Biernat, Wolfgang Schweiger

We present a relativistic point-form approach for the calculation of electroweak form factors of few-body bound states that leads to results which resemble those obtained within th…
