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.
