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.

For this purpose, three reactions have been selected: Au+Au at 1 and 1.48 A GeV and Ni+Ni at 1.93 A GeV. Kategória publikačnej činnosti ADC Číslo archívnej kópie 26409 Katal.org.
