“…The Coulomb interaction between a frozen out hadron and the strongly interacting charged hadronic matter may also be helpful in studying the evolution of the hadronic matter [2][3][4][5][6][7][8][9] . One of the advantages of studying its effects is that there is no ambiguity in constructing the electromagnetic fields if one knows completely the motion of the hadronic or quark matter.…”

An electromagnetic field produced in high-energy heavy-ion collisions contains much useful information, because the field can be directly related to the motion of the matter in the whole stage of the reaction. One can divide the total electromagnetic field into three parts, i.e., the contributions from the incident nuclei, nonparticipating nucleons, and charged fluid, the latter consisting of strongly interacting hadrons or quarks. Parametrizing the space-time evolution of the charged fluid based on hydrodynamic model, we study the development of the electromagnetic field which accompanies the high-energy heavy-ion collisions. We found that the incident nuclei bring a rather strong electromagnetic field to the interaction region of hadrons or quarks over a few fm after the collision. On the other hand, the observed charged hadrons' spectra are mostly affected ͑Coulomb effect͒ by the field of the charged fluid. We compare the result of our model with experimental data and found that the model reproduces them well. The pion yield ratio Ϫ / ϩ at a RHIC energy, AuϩAu 100ϩ100 GeV/nucleon, is also predicted. ͓S0556-2813͑99͒00609-3͔PACS number͑s͒: 25.75.Ϫq II. GLAUBER MODEL A.

“…influence of the electromagnetic field on the spectra of particles produced at mid-rapidity (that is, in the vicinity of x F = 0) in central heavy-ion reactions 1 [8][9][10][11]. However, these concentrate on the electromagnetic field induced by the presence of initial charge in the participant zone, that is, the charge of the participating nucleons 2 .…”

Abstract. In the following we stress the advantages of the NICA research programme in the context of studying the spectator-induced electromagnetic phenomena present in heavy-ion collisions. We point at the specific interest of using these phenomena as a new, independent source of information on the spacetime evolution of the reaction and of the non-perturbative process of particle production. We propose an extended series of measurements of well-defined observables to be performed in different types of nuclear reactions and in the whole range of collision energies available to NICA. We expect these measurements to bring very valuable new insight into the mechanism of non-perturbative strong interactions, complementary to the studies made at the SPS at CERN, RHIC at BNL, and the LHC.

“…However, it should be noted that the FSI depend on the structure of the emitting source and thus provide information about source dynamics as well [6]. Appreciable understanding of the particle-particle and source-particle FSI was achieved last years [7,8,9,10,11,12,13]. Meanwhile, there are several problems connected to the distortion of particle-particle FSI which are not clear enough so far.…”

Final state interactions in two-particle interferometry is considered for two-particle potentials which are the Coulomb plus "strong" one. For a simple model of the source we provide a full calculation of the correlation function with taking into account two-particle Coulomb interaction plus final state strong interaction. It is found that for small sources (R 0 = 1−4 fm) the contribution from the strong interaction is appreciable and depresses the correlations while for large fireballs (R 0 = 7 − 10 fm) this contribution is small in comparison to the Coulomb one.
