The aim of this workshop is to bring together experimentalists and theorists to discuss the various effects through which strong magnetic fields can influence the dynamics of QCD. The workshop is organized at the ECT*
in Trento, Italy from Monday 12th to Friday 16th November 2012.
In high energy heavy ion collisions the strongest magnetic fields in existence in our universe
since the times of the Big Bang are produced. With eB ~ (100 MeV)² being of a hadronic
scale and due to the very strong time dependence of these fields one has to expect that
they substantially influence QCD dynamics in the early phase of such collisions. Even more
interestingly QCD dynamics can generate topological charge changes which in turn should
lead to a coupling of magnetic to electric fields. The latter would modify the distribution
of charged particles and thus should be experimentally accessible. Charged particle correlations of the expected type might have been observed by STAR, though the experimental
situation is rather unsettled at present. These types of effects are usually discussed under
the headlines 'Chiral Magnetic Effect' (CME) and 'Local Parity Violation' where the second is
more generic and, therefore, more adequate.
Motivated primarily by the early STAR data lattice QCD groups got interested to study
the QCD phase diagram for arbitrary constant magnetic background fields. Such fields
change the localization properties and induce a spin polarization of the thermal medium
which can generate a wide spectrum of novel phenomena, including e.g. such exotic effects
like superconductivity caused by rho condensation.
