Contribution

It introduces a detailed analysis of inhomogeneous magnetic field effects on plasma expansion and particle spectra, extending previous models to include magnetic field inhomogeneity.

Findings

Magnetic fields modify transverse velocity and energy density.

Alterations in particle transverse momentum spectra observed.

Comparison with experimental data shows notable effects.

Abstract

In this paper, we study the effects of an in-homogeneous magnetic field on the quark gluon plasma dynamics, within the Magneto-Hydrodynamic framework. We have investigated the effect of an inhomogeneous external magnetic field on the transverse expansion of in-viscid fluid created in high energy nuclear collisions. Transverse velocity and energy density are modified by the presence of the magnetic field. This effects can also influence the transverse momentum spectrum for particles at the freeze-out surface. In this context we obtained an interesting comparison with data extracted from heavy-ion collisions.
