Summary: TEHRAN (FNA)- Quark matter
-- an extremely dense phase of matter made up of subatomic particles called quarks -- may exist at the heart of neutron stars.

Therefore, predicting and testing the behavior of quark matter
becomes very difficult.
They will present their latest results at the 2012 Quark Matter
conference, which starts today in Washington, DC.
This strange quark matter
is believed to be the most stable form of matter that can possibly exist in the universe.
Among the topics are nuclear magnetic resonance, from electron interaction to nuclear superfluidity, resistance in superconductors, novel phases of vortices, predicting and explaining Tc and other properties of BCS superconductors, a theory perspective on the evolution of high-temperature superconductivity, superfluidity in a gas of strongly interacting fermions, and BCS from nuclei and neutron stars to quark matter
and cold atoms.
QCD experts have predicted the existence of chunks of Strange Quark Matter
Researchers working in physics, from the US, Europe, Brazil, Mexico, and Japan discuss Cooper pairs, superconductivity in highly correlated systems, the behavior of the Bose Einstein condensation critical temperature, the plasmon exchange model in carbon nanotubes, thermodynamic properties of point node superconductors, theory of the thermopower in YBCO, high-temperature superconductivity in carbon nanotubes, and magnetism and quark matter
The findings of the PHENIX experiment -- aided by the Relativistic Heavy Ion Collider (RHIC) accelerator -- will be publicly announced during an international conference, Quark Matter
2002, that opened Thursday in Nantes, France.
QGP created at RHIC have a very low viscosity to entropy ratio, i.e., [eta]/S [greater than or equal to] l/4[pi] [4-9], and in the nonperturbative domain of QCD, with temperature close to [T.sub.c], the quark matter
in the QGP phase is strongly interacting.
The results were released at the Quark Matter
Conference recently held in Annecy, France.
