Title:
Magnetic susceptibility of QCD matter
Abstract:
In the cores of magnetars, during neutron star mergers and in heavy
ion collisions magnetic fields can be found that are so strong that
the properties of strongly interacting matter may be affected,
possibly with observable consequences. Theoretical expectation
relating to matter in such environments will be presented. These have
mostly been obtained by numerical lattice QCD computations. QCD matter
turns out to be diamagnetic at low temperatures and paramagnetic at
high temperatures. The magnetic susceptibility can be further
decomposed into a Pauli spin contribution and angular momentum related
Landau contributions. The former is related to the so-called
normalization of the photon light cone distribution amplitude.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
