Particle Production in Strong Electromagnetic Fields in Relativistic Heavy-Ion Collisions

Magnetic field 𝐁=𝐵𝐲 (multiplied by 𝑒) at the origin 𝐫=0 produced in collision of two gold ions at beam energies (a) √𝑠_𝑁𝑁=62 GeV and (b) √𝑠_𝑁𝑁=200 GeV. Adapted from [5]. Note that 𝑒𝐵 is the same in Gauss and Lorentz-Heaviside units in contrast to 𝐵.
