Mesons in non-local chiral quark models

Vector meson correlators are studied in effective chiral quark models with both local and non-local regulators. A set of sum rules based on dispersion relations is derived, which allows for a comparison of model predictions to data. We show that the two Weinberg sum rules for vector correlators hold in the non-local model.Comment: 10 pp., presented at International Workshop on Hadron Physics: Effective Theories of Low-Energy QCD, 10-15 September 1999, Coimbra, Portuga

Chiral waves in quark matter

A mini-review of non-uniform phases in quark matter is presented, with particular attention to the pion condensation, also known as chiral density waves or chiral spirals. The phase diagram of strongly-interacting matter may involve such a phase, placed on the quarkyonic island between the baryonic phase and the chirally-restored quark-gluon plasma.Comment: 10 pages, 3 figures, presented at HIC for FAIR Workshop, XXVIII Max Born Symposium "Three days on Quarkyonic Island", Wroclaw, poland, 19-21 May 201

Thermal model for RHIC, part I: particle ratios and spectra

A simple thermal model with single freeze-out and flow is used to analyze the ratios of hadron yields and the hadron transverse-mass spectra measured in 130 GeV Au+Au collisions at RHIC. An overall very good agreement between the model predictions and the data is achieved for all measured hadron species, including hyperons.Comment: Talk presented at II International Workshop on Hadron Physics, 25-29 September 2002, Coimbra, Portugal (9 pages
