Nucleons and nuclei in the context of low-energy QCD
Wolfram Weise
This presentation reports on recent developments concerning basic aspects of low-energy QCD as they relate to the understanding of the nucleon mass and the nuclear many-body proble…
Beta-decay rates of r-process nuclei in the relativistic quasiparticle random phase approximation
T. Niksic, T. Marketin, D. Vretenar +2
The fully consistent relativistic proton-neutron quasiparticle random phase approximation (PN-RQRPA) is employed in the calculation of beta-decay half-lives of neutron-rich nuclei…
Nuclear density functional constrained by low-energy QCD
Paolo Finelli, Norbert Kaiser, Dario Vretenar +1
We have developed a relativistic point-coupling model of nuclear many-body dynamics constrained by the low-energy sector of QCD. The effective Lagrangian is characterized by densit…
Nucleon Polarisabilities from Compton Scattering off the One- and Few-Nucleon System

These proceedings sketch how combining recent theoretical advances with data from the new generation of high-precision Compton scattering experiments on both the proton and few-nuc…
Nuclear pairing from chiral pion-nucleon dynamics
N. Kaiser, T. Niksic, D. Vretenar
We use a recently improved version of the chiral nucleon-nucleon potential at next-to-next-to-leading order to calculate the pairing gap in isospin-symmetric nuclear matter…

We present a novel approach to the density dependent mean field and the spin-orbit interaction of a -hyperon in a nuclear many-body system, based on flavor-SU(3) in-medium chira…
Spin-asymmetry energy of nuclear matter

We calculate the density-dependent spin-asymmetry energy of isospin-symmetric nuclear matter in the three-loop approximation of chiral perturbation theory. The interaction…
Deuteron Compton Scattering: A Random Walk
Harald W. Griesshammer
In this sketch, some recent developments in Compton scattering off the deuteron are reviewed. The strong energy-dependence of the scalar magnetic dipole polarisability β_M1 turns o…
Alternative Interpretation of Sharply Rising E0 Strengths in Transitional Regions
P. von Brentano, V. Werner, R. F. Casten +4
It is shown that strong 0+2 -> 0+1 E0 transitions provide a clear signature of phase transitional behavior in finite nuclei. Calculations using the IBA show that these transition s…

The pseudorapidity dependence of anisotropic flows , , , and of charged hadrons in heavy-ion collisions at the Relativistic Heavy Ion Collider is stud…
Spin-orbit coupling in nuclei and realistic nucleon-nucleon potentials

We analyze the spin-orbit coupling term in the nuclear energy density functional in terms of a zero-range NN-contact interaction and finite-range contributions from two-pion exchan…
Hydrodynamic aspects of relativistic heavy ion collisions at RHIC

The current status of the application of hydrodynamics to ultrarelativistic heavy ion collisions is reviewed. We elaborate on the arguments for strong transverse flow and rapid the…
