Theory Highlights of Quark Matter 2004

Selected highlights of the theoretical developments reported at the 2004 Quark Matter conference are discussed, with emphasis on open issues.

Strange quark matter attached to string cloud in general scalar tensor theory of gravitation

Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...

Theory at Quark Matter ’ 02

The collisions of large nuclei may give us insight into the nature of QCD at high temperatures and/or densities. In this talk I review the status of theory for heavy ion collisions from Quark Matter 2002. I concentrate on the the results for the largest nuclei, with atomic number A ≈ 200. At the SPS at CERN, there are two notable results for AA collisions, for √ s/A : 5 → 17 GeV [1]: J/Ψ suppre...

Effective Theory of Superfluid Quark Matter

We provide a brief introduction to the high density effective theory of QCD. As an application, we consider the instanton correction to the perturbatively generated gap in the color superconducting phase. We show that the instanton correction becomes large for μ ∼ 1.25 GeV in Nf = 2 QCD, and for μ ∼ 750 MeV in Nf = 3 QCD with a massive strange quark. We also study some other numerical issues re...
