"QCD tales: quarks and pions"
Dr. José Rodríguez-Quintero
Universidad de Huelva, España
I will review some recent works where, with the help of
non-perturbative methods for the investigation in QCD as
lattice field theory or Dyson-Schwinger equations, the
effects from the number of light-fermion flavours on gluon
and quark propagation are scrutinized. Conclusions about
QCD chiral symmetry restoration and confinement will be
inferred. I will also present a recent study for the pion
parton distributions (PDF and GPD), again, exploiting the
non-perturbative Dyson-Schwinger and Bethe-Salpeter
approaches to get a simple but instructive model, as a
first step paving the way towards a better understanding
of hadron dynamics from QCD.
