Quark pair creation in color electric fields and effects of magnetic fields

Understand

The time evolution of a system where a uniform and classical SU(3) color electric field and quantum fields of quarks are dynamically coupled with each other is studied focusing on non-perturbative pair creation and its back reaction.

• We characterize the color direction of the electric field in a gauge invariant way, and investigate its dependence.
• Momentum distributions of created quarks show plasma oscillation as well as quantum effects such as the Pauli blocking and interference.
• Pressure of the system is also calculated, and we show that pair creation moderates degree of anisotropy of pressure.
