TL;DR: In this article, the authors measured directed and elliptic flows of neutrons and light charged particles for the reaction 197Au+197Au at 400 MeV/nucleon incident energy within the ASY-EOS experimental campaign at the GSI laboratory.
Journal ArticleDOI
Constraining the nuclear matter equation of state around twice saturation density
TL;DR: In this paper, the authors extract constraints for the equation of state (EOS) of compressed symmetric nuclear matter using the transport code IQMD by introducing an observable describing the evolution of the size of the elliptic flow as a function of rapidity.

TL;DR: Using the invariant mass method, the spectroscopy of hypernuclear products of 6Li projectiles on a carbon target at 2 A GeV was performed in this paper, where the lifetime values were deduced to be 262 − 43 + 56 ± 45 ps for Λ, 183 − 32 + 42 ± 37 ps for H Λ 3, and 140 − 33 + 48 ± 35 ps for h Λ 4.

TL;DR: In this paper, the authors used the transverse energy of light particles as an impact parameter selector and compared the results with dynamical models with which a good agreement was obtained. But the results were not compared to dynamical model with which good agreement is obtained.

TL;DR: Yield ratios for light particles and fragments with atomic number Z < or = 5 obey the exponential law of isotopic scaling, and deduced scaling parameters decrease strongly with increasing centrality to values smaller than 50% of those obtained for the peripheral event groups.
