Short lived hadronic resonances are a very important tool for the study of the dynamics of the matter produced in heavy-ion collisions since they should be sensitive to the medium properties such as temperature, density and expansion…
Nuclei are nearly transparent to each other when they collide at high energy, but the collisions do produce high energy density matter in the central rapidity region where most experimental measurements are made. What happens to the…
In very high energy collisions nuclei are practically transparent to each other but produce very hot, nearly baryon-free, matter in the so-called central rapidity region. The energy in the central rapidity region comes from the kinetic…
