Effects of compression and collective expansion on particle emission from central heavy-ion reactions
Effects of compression and collective expansion on particle emission from central heavy-ion reactions
Conditions under which compression occurs and collective expansion develops in energetic symmetric reactions of heavy nuclei are analyzed, together with their effects on emitted light baryons and pions. Within transport simulations, it is shown that shock fronts perpendicular to beam axis form in head-on reactions. The fronts separate hot compressed …
