1 PublicationProbing in-medium vector meson decays by double-differential di-electron spectra in heavy-ion collisions at SIS energies
Kämpfer, B.; Pavlenko, O.; Wolf, G.
Abstract
Within a transport code simulation for heavy-ion collisions at bombarding energies around 1 AGeV we demonstrate that double-differential di-electron spectra with suitable kinematical cuts are useful to isolate
(i) the ρ meson peak even in case of strong broadening, and
(ii) the in-medium ω decay contribution,
which probe via the di-electron channel the expected in-medium modifications of the vector meson spectral densities.
Keywords: heavy-ion collisions; di-electrons; in-medium modifications of vector mesons
