DESCRIPTION:Speakers: Prof. EL-BENNICH\, Bruno (Cruzeiro do Sul University
 )\nWhether a mass gap occurs in QCD\, and therefore DCSB leading to consti
 tuent masses\, depends on the DSE kernel. One crucial ingredient is the qu
 ark-gluon vertex whose structure is complex once dressed with gluons. We u
 se QCD gauge identities and multiplicative renormalizability to derive the
  form factors of the vertex and combine them with lattice QCD gluon and gh
 ost propagators. Solving numerically the DSE shows that the induced DCSB i
 s very large and produces a realistic constituent-quark mass.\n\nhttps://i

DESCRIPTION:Speakers: Dr. NARCISO FERREIRA\, Mauricio (IFGW-UNICAMP)\nWe s
 tudy the coupled dynamics of the ghost propagator and the ghost-gluon vert
 ex through  Schwinger-Dyson equations. To close the system\, we use recent
  lattice data for the gluon propagator and a Gauge Technique Ansatz for th
 e three-gluon vertex. The numerical results for the ghost propagator and g
 host-gluon vertex agree excellently to lattice data. Finally\, a consisten
 cy check is done in the soft gluon limit where the full three-gluon vertex
  appearing in the equations is fixed by lattice data.\n\nhttps://indico.nu

DESCRIPTION:Speakers: Prof. DE MELO\, Joao Pacheco (Laboratorio de Fisica 
  Teorica e Computacional - LFTC - UCS / UNICID)\nThe pion meson in the  pr
 esent work  is describe in  the Nakanish Integral representation (NIR)\, f
 or the Bethe-Salpeter amplitude\, combined with the Lattice QCD. The quark
  mass running is fitted by the Lattice data.  The results for the weak dec
 ay constant are \n           found to be consistent with the experimental 
 data. \nAlso the valence probabilities  and the  Light-front distribuition
 s are explored.\n\nhttps://indico.nucleares.unam.mx/event/1541/session/64/
