Parallel session 32: Correlations & fluctuations III
- Horst Stoecker (GSI)
This presentation discusses recent results on femtoscopic correlations involving $D^0$ ($\bar{D0}$) mesons and hyperon polarization in pPb collisions at $\sqrt{s_{NN}}=8.16$ TeV. The femtoscopic measurements investigate the strong interaction for pair combinations of particles, allowing to extract the scattering observables accessible through their correlation functions. The results may...
Measurements of identical pion femtoscopy offer insights into collision dynamics, such as collective expansion, geometry of the collision zone at freeze-out, etc. In addition to the quantum interference among the pion pairs, Coulomb interactions between the pair and the net positive charge in the emitting source affect the final measurements as well. Furthermore, due to the imbalance of...
Heavy-ion collisions offer a new way to understand hyperon-nucleon ($Y$-$N$) interactions. The two-particle correlation in pair relative momentum, which reveals valuable information about the space-time evolution of the particle-emitting source and final state interactions involving hyperons, is the primary observable of interest. The measurements of correlations between light nuclei ($d$,...
The three-dimensional structure of the initial state in heavy-ion collisions have become important topic of interest in the community, since it provides insights into the origins of anisotropic flow, the breaking of boost invariance, longitudinal de-correlation, and particle correlations observed after kinetic freeze-out. One of the important properties of the 3D initial state is the tilt of...
Short-range correlations among hadrons in relativistic heavy-ion experiments are typically regarded as non-hydrodynamic and subtracted from the data. However, the fluid nature of the quark-gluon plasma (QGP) gives rise to short-range correlations stemming from hydrodynamic fluctuations. These correlations, driven by fluctuation-dissipation relations near local equilibrium, provide key insights...
