Description
Summary:The strongest electromagnetic fields in nature are created in high energy nuclear collisions and expected to change the dynamic scattering processes in the early stage. The magnetic field effect on the Drell-Yan process is investigated in this work. The single photon decay into quark pairs and lepton pairs in an external magnetic field leads to a significant Drell-Yan suppression in low and intermediate invariant mass region. The calculation up to the Landau level n−1 is complete in the energy region s<2/3n(eB), and the enlarged phase space at higher landau levels may enhance the dilepton spectrum in the high mass region.
