The creation of loosely bound light (anti-)(hyper-)nuclei in heavy ion collisions near the phase transition temperature (Tch≈155 MeV) has been a puzzling observation. We solve this puzzle by showing that the light cluster abundancies in heavy ion reactions stay approximately constant from chemical freeze-out to kinetic freeze-out. To this aim we develop an extensive network of coupled reaction...
A hydrodynamic approach to the transport of heavy quarks in the quark-gluon plasma (QGP) is presented. We exploit the conservation of the number of heavy quark-antiquark pairs within the evolution of the plasma to construct causal second-order hydrodynamic equations of motion. The hydrodynamic transport coefficients associated to the heavy-quark diffusion current are then compared with the...
Quarkonium suppression has long been regarded as a potential probe of
deconfinement in nucleus-nucleus collisions. Recently, the production of 𝐽/𝜓 via regeneration within the QGP or at the phase boundary has been identified as an important ingredient for the interpretation of quarkonium production results from lead-lead collisions at the Large Hadron Collider (LHC). Moreover, the study of the...
The search for Triaxial Superdeformed (TSD) bands in the N~90 isotones has been a subject of interest for the past two-three decades [1-7]. The focus on these studies has been mainly confined to ultra-high spin states. In these studies, high spin structures with enhanced deformation have been reported and associated with the phenomenon of Triaxial Superdeformation.
The phenomenon of TSD...
