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

Figure 5

Time dependence of electric field due to the Schwinger mechanism back reaction and the corresponding electric current density of Schwinger pairs. Dimensionless time variable is defined as 𝜏=𝑡/𝜆^-. For electrons 𝜆^-=380 fm. Plasma undergoes phase transition at about 𝜏=1/38. Adapted from [6].
