Type: Parallel Session: QCD and hadron structure-A7
Track: QCD and Hadron Structure
We study the coupled dynamics of the ghost propagator and the ghost-gluon vertex through Schwinger-Dyson equations. To close the system, we use recent lattice data for the gluon propagator and a Gauge Technique Ansatz for the three-gluon vertex. The numerical results for the ghost propagator and ghost-gluon vertex agree excellently to lattice data. Finally, a consistency check is done in the soft ... More

Type: Parallel Session: QCD and hadron structure-A7
Track: QCD and Hadron Structure
The pion meson in the present work is describe in the Nakanish Integral representation (NIR), for the Bethe-Salpeter amplitude, combined with the Lattice QCD. The quark mass running is fitted by the Lattice data. The results for the weak decay constant are found to be consistent with the experimental data. Also the valence probabilities and the Light-front distribuitions are e ... More

Type: Parallel Session: QCD and hadron structure-A7
Track: QCD and Hadron Structure
Whether a mass gap occurs in QCD, and therefore DCSB leading to constituent masses, depends on the DSE kernel. One crucial ingredient is the quark-gluon vertex whose structure is complex once dressed with gluons. We use QCD gauge identities and multiplicative renormalizability to derive the form factors of the vertex and combine them with lattice QCD gluon and ghost propagators. Solving numericall ... More
