Pair creation in boost-invariantly expanding electric fields and two-particle correlations
arXiv:1010.4516 · doi:10.1103/PhysRevD.83.045011
Abstract
Pair creation of scalar particles in a boost-invariant electric field which is confined in the forward light cone is studied. We present the proper-time evolution of momentum distributions of created particles, which preserve the boost invariance of the background field. The two-particle correlation of the created particles is also calculated. We find that long-range rapidity correlations may arise from the Schwinger mechanism in the boost-invariant electric field.
