We describe how parton recombination can address the recent measurement of dynam-ical jet-like two particle correlations. In addition we discuss the possible effect realistic light-cone wave-functions including higher Fock-states may have on the well-known elliptic flow valence-quark number scaling law.

Abstract We investigate, in microcanonical multifragmentation models, the influence of the amount of energy dissipated in break-up fragments excitation on freeze-out volume determination. Assuming a limiting temperature decreasing with nuclear mass, we obtain for the Xe+Sn at 32 MeV/nucleon reaction [J. D. Frankland et al., Nucl. Phys. A689, 905 (2001); A689, 940 (2001)] a freeze-out volume alm...

Our contribution to the Eta’05 workshop on “Production and Decay of η and η Mesons” (1518.9.2005, Cracow, Poland) is summarized. First we discuss open questions in the theoretical treatment of Coulomb-interaction in the context of reaction processes like pp → ppη. Then we review η-η and σ(600)-f0(980) mixing in the U(3)×U(3) Linear Sigma Model and extract information on η-η mixing and the K 0 (...
