    Evidence for creation of strong electromagnetic fields in relativistic heavy-ion collisions

    V. Toneev🇷🇺 · O. Rogachevsky🇷🇺 · V. Voronyuk🇺🇦

    It is proposed to identify a strong electric field created during relativistic collisions of asymmetric nuclei via observation of pseudorapidity and transverse momentum distributions of hadrons with the same mass but opposite charges. The detailed calculation results for the directed flow within the Parton-Hadron String Dynamics model are given for Cu-Au interactions at the NICA collision energies of and GeV. The separation effect is observable at 9 GeV as clearly as at 200 GeV

    Holographic Collisions in Non-conformal Theories

    Maximilian Attems🇪🇸 · Jorge Casalderrey-Solana🇪🇸 · David Mateos🇪🇸 · Daniel Santos-Oliván🇪🇸 · Carlos F. Sopuerta🇪🇸 · Miquel Triana🇪🇸 · Miguel Zilhão🇪🇸

    We numerically simulate gravitational shock wave collisions in a holographic model dual to a non-conformal four-dimensional gauge theory. We find two novel effects associated to the non-zero bulk viscosity of the resulting plasma. First, the hydrodynamization time increases. Second, if the bulk viscosity is large enough then the plasma becomes well described by hydrodynamics before the energy density and the average pressure begin to obey the equilibrium equation of state. We discuss implications for the quark-gluon plasma created in heavy ion collision experiments.
