Heavy Ion Collisions
Collision of two uranium nuclei at 23 GeV/nucleon
is a great challenge to understand the processes, which led to the creation of
the physical world around us. In the Big Bang theory, a singularity in time
started the existence of our universe, its evolution thereafter being determined
by physical processes that occur in different time scales.
genesis, the formation of baryonic matter, is believed to have formed on a time
scale of 10 to 20 microseconds after the beginning. The Understanding of the
behaviour of baryonic matter is of central importance since baryonic matter
serves as a building block of all the atoms we know today.
only way of studying baryonic genesis in the laboratory is by means of
high-energy heavy-ion collisions. In such collisions, nuclear matter is produced
at high density and high temperature, and thus creating the physical environment
necessary for the study of those phenomena that appeared in the early universe.
Laboratory participates in the international HADES collaboration at GSI
Darmstadt/Germany. The HADES project represents
a major scientific program of GSI, and is unique worldwide with respect to both
its innovative technical design and physics questions addressed.
