Description |
The presence of intense transient magnetic field (108- 1019 Gauss for a
typical c.m. collision energy of √sNN = 200 GeV Au + Au collision) in the
initial stage of high energy heavy ion collisions at RHIC and LHC may
results in varieties of new experimental observations including global
electric charge separation predicted by Quantum Chromodynamical calculations.
Moreover, the strong magnetic and electric fields in the initial stage may
also modify the initial energy density profile as well as the subsequent
hydrodynamics evolution of the Quark Gluon Plasma phase. In this work we
evaluate the contribution of electric and magnetic fields on the initial
energy density distribution for √sNN = 200 GeV Au + Au collisions using a
Monte-Carlo Glauber model. We also discuss the magnetohydrodynamics evolution
of a perfectly conducting (zero electrical resistivity) fluid undergoing Bjorken boost invariant expansion in the longitudinal direction.
