2. The phase transition and the critical point
Dedicated experiment looking for critical phenomena at
SPS (?) or FAIR(GSI) in 2015

The future GSI Project - FAIR
• Facility for Antiproton and heavy Ions
Research
• Planned commissioning: 2010 – 2015
• CBM experiment
– super-dense baryonic matter
– in-medium properties of hadrons

3.
Dense matter in the universe –
exotic QCD matter (color superconductor)
15
Dense Matter in the Universe
• Mergers of binary stars – the ultimate nuclear collision
– evolution depends on the equation-of-state of the matter inside the
star
– large differences between normal neutron stars and selfbound stars
– different pattern of mass transfer
– observable via gamma bursts, gravitational waves, ...? in 2020?

Conclusion
•
Nuclear Physics 1932:
protons, neutrons and quantum mechanics
”We have all that. I think in six months we’ll have
[description of] the proton, and physics as we know it will
be over.”
Max Born to Isidor Rabi, after the Dirac equation (1928)
•
Nuclear Physics 1948: pion
”I remember at the Pocono meeting that Robert
Oppenheimer said ‘Now we have field theory in hand’ and
I remember vividly that Rabi got up and said ‘What the
hell shall I measure now?’ There was the sense that one
was very close to the end. And then, of course, came the
great disillusions...”
Julian Schwinger (1980)
