摘要
This paper focuses on studies of spectator-induced electromagnetic (EM) effects on charged pion emission observed for three different colliding systems: Pb+gas, peripheral Pb+Pb and Ar+Sc collisions at CERN SPS energies. New data on Ar+Sc collisions from the NA61/SHINE experiment bring a first insight into EM effects in small systems. In this paper, we present the improvement of our phenomenological model description which takes into account spectator fragmentation as well as the possible influence of the net positive participant charge close to the spectator system.
