Importance of Magnetic Field on Hydrodynamics Evolution in Heavy Ion Collisions

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.
