Abstract:
Relativistic collisions of heavy ions lead to the formation of a new phase of matter called Quark-Gluon Plasma (QGP). In addition, strong magnetic fields generates in these collisions that its direction is perpendicular to the collision axis. This strong magnetic field affects the dynamics of particles in the QGP, and causes the appearance of the Landau levels in the particle’s energy spectrum. In this master thesis, we investigate the impact of the magnetic field on dilepton production and synchrotron radiation. We calculate the scattering probability of quark and anti-quark annihilation and dilepton creation by taking all Landau Levels into account. Then, by assuming that the magnetic field is very strong, we find an expression for the scattering cross-section of dileptons in the lowest Landau level, and show that by increasing the strength of the magnetic field, the scattering cross- section increases too. To study the synchrotron radiation, we obtain a relation for its spectral distribution, and study its dependence on the magnetic field
