Spacetime profile of electromagnetic fields in intermediate-energy heavy-ion collisions

Year: 2025

Type: article

Abstract: I numerically estimate the spacetime profile of the electromagnetic fields produced in intermediate-energy heavy-ion collisions at s N N = 2.4 – 7.7 GeV for a wide range of impact parameters b = 0 – 9 fm , using a hadronic cascade model, (Jet AA Microscopic transport model). I demonstrate that (1) the produced electromagnetic fields are as strong as e E , e B = O ( ( 50 MeV ) 2 ) ; (2) that the produced fields extend in spacetime about V 4 = O ( ( 10 fm ) 4 ) ; (3) that the magnetic field dominates around the collision point, while the other broad regions of spacetime are dominated by the electric field; and (4) that a topological electromagnetic-field configuration such that E · B ≠ 0 is realized.
