Naive Gaussian approximation in a quark-meson model
Győző Kovács, Zsolt Szép, Péter Kovács +1
A sequence of approximations is derived to go beyond the mean-field level in the case of a simple linear sigma model. A naive, local version of the Gaussian approximation is discus…
Chiral symmetry, di-electrons and charm
B. Kampfer, T. Hilger, H. Schade +2
We survey some prospects of identifying further in-medium modifications of hadrons in a strongly interacting medium with respect to ongoing experiment series of the HADES Collabora…
Production of phi mesons in subthreshold heavy-ion collisions
M. Zetenyi, H. W. Barz, Gy. Wolf +1
Within a BUU type transport model we study meson production in subthreshold Ni+Ni and Ru+Ru reactions. For the first time we included in our model the elementary reaction chann…
Subthreshold phi-meson production in heavy-ion collisions
H. W. Barz, M. Zetenyi, Gy. Wolf +1
Within a transport code of BUU type the production of phi-mesons in the reactions Ni+Ni at 1.93 AGeV and Ru+Ru at 1.69 AGeV is studied. New elementary reaction channels rho+N(Delta…
Pion-nucleus reactions in a microscopic transport model
A. Engel, W. Cassing, U. Mosel +2
We analyse pion-nucleus reactions in a microscopic transport model of the BUU type, which propagates nucleons, pions, deltas and N(1440)-resonances explicitly in space and time. In…
