TL;DR: It is demonstrated that, in the absence of a direct measurement, the full spacelike doubly virtual pion transition form factor can be reconstructed very accurately based on existing data, and a representation is derived that incorporates all the low-lying singularities of the form factor, matches correctly onto the asymptotic behavior expected from perturbative QCD.

TL;DR: In this article, the authors present a consistent theoretical approach for the study of nonequilibrium effects in chiral fluid dynamics within the framework of the linear $\ensuremath{\sigma}$ model with constituent quarks.

TL;DR: In this article, the in-medium properties of mesons ( π, η, ρ ) and baryon resonances in cold nuclear matter within a coupled-channel analysis were studied.

TL;DR: In this paper, the decays of narrow light vector mesons into pseudoscalar mesons and dileptons are calculated to leading order in a recently proposed scheme which treats pseudosalar and vector meson on equal footing.

TL;DR: In this paper, the current understanding of the dynamics of critical fluctuations in QCD and their measurement in heavy-ion collision experiments is discussed, and what might be learned from studying correlations in other physical systems, such as cold atomic gases.
