NuSym23, XIth International Symposium on Nuclear Symmetry Energy

New insights into the nuclear symmetry energy and related formation of neutron skin in nuclei have been gained through recent precise parity-violating electron scattering experiments on $^{48}$Ca (CREX) and $^{208}$Pb (PREX-II). To understand the implications of these experiments for the nuclear energy density functionals (EDF), consistent investigation is required to address the nuclear...

The electric dipole polarizability is a key observable for the understanding of nuclear matter. Strong correlations between the neutron skin thickness, the dipole polarizability and the parameters of the symmetry energy term in the equation of state of neutron rich matter have been found within the framework of energy density functional theory [1].
The polarizability is experimentally...

The neutron-skin thickness is one of the most robust probes of the slope parameter of the nuclear symmetry energy, which is responsible for the main uncertainty of the nuclear matter equation of state. Relativistic heavy-ion collisions may serve as a complementary measurement of the neutron-skin thickness, in addition to various methods in nuclear structure studies. In these collisions, we...

An experiment measuring the Coulomb-excitation cross section, σC [1] in neutron-rich tin nuclei
( 124 Sn– 134 Sn) at relativistic energies was performed at GSI, Darmstadt with the aim to constrain
the slope of the symmetry energy, L. This particular cross section correlates with dipole polariz-
ability, α D , a well-established observable for constraining L [2], which enables achieving the...

Here we provide experimental evidence for an increasing nuclear symmetry energy for nuclei at temperatures typically found in neutron mergers and collapsars, which may lead to the close in of the nuclear chart (or neutron dripline) at the limits of stability, and constrain the paths of various r-process nucleosynthesis mechanisms; hence, supporting the universal pattern of abundances for...

This contribution reviews a selection of available constraints to the nuclear symmetry energy around saturation density from nuclear structure calculations on ground and collective excited state properties of atomic nuclei. Special focus will be given to the parity violating asymmetry and dipole polarizability in 48Ca and 208Pb. Phenomenologic as well as microscopic results --whenever...

Nuclear many-body system is a self-organizing active matter, which has seemingly contradictory aspects of uniform single-particle matter and non-uniform cluster-forming matter. Recently, we have launched two complementary experimental programs "ESPRI/ONOKORO" to study uniform/non-uniform properties in nuclei and nuclear matter. In the projects, direct reaction methods with hadronic probes at...

Isobar $^{96}_{44}$Ru+$^{96}_{44}$Ru and $^{96}_{40}$Zr+$^{96}_{40}$Zr collisions at nucleon-nucleon center-of-mass energy of 200 GeV at the Relativistic Heavy Ion Collider (RHIC) were initially proposed as a decisive experiment on the chiral magnetic effect, presuming identical QCD background [1]. They turned out to be rather different, by, for instance, as large as 5% in multiplicity [2]....
