Query: Strong interactions: From methods to structures   These are the proceedings of the workshop on "Strong interactions: From
methods to structures" held at the Physikzentrum Bad Honnef of the Deutsche
Physikalische Gesellschaft, Bad Honnef, Germany from February 12 to 16, 2011.
The workshop concentrated on physics of cold atoms, chiral perturbation theory
for mesons and baryons, chiral dynamics in few-baryon systems and effective
field theories for systems with heavy quarks. Included are a short contribution
per talk.
