    AnnotationIt is proposed to identify a strong electric field-created during relativistic collisions of asymmetric nuclei-via the observation of pseudorapidity and transverse momentum distributions of hadrons with the same mass but opposite charge. The results of detailed calculations within the parton-hadron string dynamics (PHSD) approach for the charge-dependent directed flow v(1) are presented for semicentral Cu+Au collision at root S-NN = 200 GeV incorporating the inverse Landau-Pomeranchuk-Migdal (iLPM) effect, which accounts for a delay in the electromagnetic interaction with the charged degrees of freedom. By including the iLPM effect, we achieve a reasonable agreement of the PHSD results for the charge splitting in v(1)(p(T)) in line with the recent measurements by the STAR Collaboration for Cu+Au collisions at root s(NN) = 200 GeV while an instant appearance and coupling of electric charges at the hard collision vertex overestimates the splitting by about a factor of 10. We predict that the iLPM effect should practically disappear at energies of root s(NN) approximate to 9 GeV, which should lead to a significantly larger charge splitting of v1 at the future FAIR/NICA facilities.

    AnnotationIn this paper we review recent progress on the systematic evaluation of the kaon and antikaon spectral functions in dense nuclear matter based on a chiral SU(3) description of the low-energy pion-, kaon- and antikaon-nucleon scattering data.

    AnnotationProduction of phi mesons is considered in the course of heavy-ion collisions at SPS energies. We investigate the possible difference in momentum distributions of phi mesons measured via their leptonic (mu (+),mu (-)) and hadronic (K+ K-) decays. Rescattering of secondary kaons in the dense hadron gas together with the influence of in-medium kaon potential can lead to a relative decrease of the phi yield observed in the hadronic channel. We analyze how the in-medium modifications of meson properties affect apparent, reconstructed momentum distributions of phi mesons. Quantitative results are presented for central Pb+Pb collisions at E-beam = 158 GeV/nucleon.
