39. Tight Symmetry Energy Parameter Constraints from Neutron Skin Measurements

JAMES LATTIMER (Stony Brook University)

Overview Talk

Inferences of nuclear symmetry energy parameters from recent parity-violating neutron skin measurements of the neutron-rich nuclei Ca-48 and Pb-208 appear to be in tension not only with each other but also with values obtained from fitting either nuclear masses or neutron matter theory. By themselves, PREX I+II measurements of Pb-208 and CREX measurement of Ca-48 suggest $L\simeq110\pm36$ MeV...

82. Charm quarks from production to hadronisation in heavy–ion collisions

Dr Fabrizio Grosa (CERN)

26/01/2023, 11:00

Overview Talk

Given their large mass, charm quarks are recognised as powerful probes of the colour-deconfined state of the matter called quark–gluon plasma (QGP) created in high-energy heavy–ion collisions. They are mainly pro- duced in high-momentum transfer processes in shorter timescales compared to the QGP formation time, and they subsequently experience the full sys- tem evolution interacting with the...

5. Exotic mesons with functional methods

Extended Contribution

We summarize recent results on exotic mesons determined in the framework of functional methods (Dyson-Schwinger and Bethe-Salpeter equations) in QCD.
We cover results on glueballs and four-quark states as well as their mixing
with conventional mesons in the light quark sector of QCD. In the charmoninum region we shed light on the internal structure of heavy-light four-quark states with...
