Query: Hyperon-rich matter   The phase diagram of nuclear matter is extended to strangeness and
antimatter. It offers fascinating features for heavy ion physics and
astrophysics. We will discuss some regions of this phase diagram as strange
matter at zero temperature, hypermatter at high densities and the antiworld at
high densities and strangeness fraction.
