Overview of Conference
IVth International Conference on Quarks and
Nuclear Physics which was held in Madrid, Spain
from June 5-10, 2006. The conference was held at
the Universidad Complutense de Madrid.
The goal of the conference is to advance the
knowledge of the strong interactions. We intend
to cover a broad spectrum of topics in both
Nuclear and Particle physics. The conference
will be structured in two parts, with technical
talks scheduled first and review talks in the
last days. There will be a poster session.
Here is a brief list of session topics Lattice,
Meson Physics, Baryon Physics, Light Meson
Spectroscopy, Hadron Structure, Heavy Quarks,
Non-perturbative QCD, Topics in Nuclear
Physics, Matter Under Extreme Conditions, Some
Classic QCD Topics, .

Some Classic QCD Topics

• Session chair was Craig Roberts of ANL.
• Session Program
• Preliminary Results of the Primex Experiment - me
• On Dynamical Gluon Mass Generation - Joannis
  Papavassiliou (Barcelona)
• Infrared Properties of QCD from  Dyson-Schwinger
  Equations - Christian S. Fischer
• Aspects of QCD Modeling for Hadrons and Form
  Factors Peter Tandy (Kent State U.)

• Jerry Miller of U. of Washington Any new
  theory calculations?
• Lengthy discussion with Craig Roberts during the
  coffee break. He is
• interested in this results. He also asked about
  measuring the Primakoff
• effect of the p(1300).

Primakoff Effect and p(1300)
C. Roberts has 2 papers on radial excitations of

and excited state pseudoscalar mesons A. Höll,

According to his theory, the ground p0 is
interesting since it comes primarily from the
chiral anomaly. The heavier pions are
complimentary since the chiral anomaly plays
almost no role, and the main contribution is from
QCD dynamics.

• Experimental problems
• The Primex setup would not detect the p(1300)
  even at 11 GeV.
• The PDG has no information on p(1300), and its
  width is estimated at
• 200-500 MeV.

Final Thoughts

• There were a wide variety of topics from
  few-nucleon physics to RHIC.
• Primex experiment was received well, even if it
  was just a few people.
• Majority of the talks were from theorists.
• Conference length (6 days) was 1 day too long.
• All in all, I enjoyed the conference very much.
