48. Nuclear Structure Aspects from Gamma‐decay from Giant Resonances

Prof. Angela Bracco

Measurements of gamma-decay from giant resonances (including the their tail regions) are important to probe in detail the properties of these states and thus to test theoretical predictions based on mean fields. This presentation focuses mainly on two aspects concerning the electric dipole excitation in nuclei. The first is the study of the low energy tail of the Giant Dipole Resonance...

50. Interplay between Spin and Isospin in Exotic Nuclei

Nuclear physics in the 20th century succeeded in finding regularities in stable nuclei and in establishing a reasonable picture of a “nucleus”. In 1937, Wigner presented a picture, referred as “supermultiplet theory”, on a basis of deep consideration on symmetry in a proton and neutron system. We must be surprised that Wigner captured an essence of nuclear structure with little knowledge...

49. Towards experiments at the new ELI-NP facility

Prof. Dimiter Balabanski

The Extreme Light Infrastructure (ELI) Pan-European facility initiative represents a major step forward in quest for extreme electromagnetic fields. Extreme Light Infrastructure – Nuclear Physics (ELI-NP) is one of the three pillars of the ELI facility, that aims to use extreme electromagnetic fields for nuclear physics and quantum electrodynamics research. At ELI-NP, high power laser systems...

51. Symmetries and in-medium effects

Prof. Volker Metag

Chiral symmetry is a fundamental symmetry of Quntum Chromodynamics (QCD) in the limit of vanishing quark masses. In the hadronic sector chiral symmetry is broken; otherwise chiral partners – hadronic states with the same spin but opposite parity - should be degenerate in mass which is not observed in nature. It has been suggested that chiral symmetry might at least partially be restored in a...

52. Polyakov loop and charge fluctuations as probes of QCD phase transition

Prof. Krzystof Redlich

12/11/2013, 16:00

We discuss the properties of the Polyakov loop and baryon number fluctuations as probes for the deconfinement and the chiral phase transition in QCD. The arguments will be presented in the context of Lattice QCD and an effective chiral model calculations based on the functional renormalisation group. We connect theoretical findings with experimental data.

79. QGP Hadronization: Universal Conditions at SPS, RHIC and LHC

Prof. Johann Rafelski

12/11/2013, 16:25

We study properties of the expanding quark-gluon plasma (QGP) fireball and the principles governing QGP hadronization, employing the statistical hadronization model (SHM) description of particle production in relativistic heavy-ion collisions. We show that the chemical non-equilibrium model gives a very good description of the hadron production in entire energy range including the LHC...
