Clusters and condensates in quark and nuclear matter — •M. Beyer1, S. Mattiello1, S. Strauss1, T. Frederico2, P. Schuck3, S. A. Sofianos4, and H.-J. Weber5 — 1Univ Rostock — 2CTA Sao Paulo — 3IPN Orsay — 4UNISA Pretoria — 5Univ of Virginia
We investigate cluster and condensation phenomena in the QCD phase diagram using suitably extended few-body equations of Alt-Grassberger-Sandhas resp. Faddeev type. These equations are based on a systematic Dyson approach to many-body systems and include self energy corrections and Pauli blocking. At lower densities and temperatures we study three- and four-nucleon clusters, and α-particle condensation. At higher energies we study the transition region from quark to nuclear matter where three-quark states cluster to nucleons. To treat special relativity in this regime we use the light front form.
