Production of Strange, Non-strange particles and Hypernuclei in an Excluded-Volume Model
We present a systematic study of production of strange and non-strange hadron yields and their ratios obtained in various experiments using our thermodynamically consistent excluded-volume model. We also analyze the production of light nuclei, hypernuclei and their antinuclei in terms of our excluded-volume model over a broad energy range starting from Alternating Gradient Synchrotron (AGS) to Large Hadron Collider (LHC) energies. Further, we extend our model for studying rapidity spectra of hadrons produced in heavy-ion collisions.
Abstract Recently, a large enhancement of the dilepton yield in nuclear collisions was discovered at the CERN SPS. These data triggered a considerable theoretical effort searching for explanations. In my talk the experimental evidence for the dilepton enhancement and the present status of understanding is reviewed.
