Vacuum instability by a chromoelectric field in 2 + 1-dimensions
arXiv:1310.2875 · doi:10.1103/PhysRevD.89.014019
Abstract
The problem of vacuum instability and creation of pairs by external fields SU(2) is studied. The effective mass operator has complex eigenvalues implying decay and pair creation. We consider a constant external chromoelectric field and a region in the parameter space where the vaccum becomes unstable and decays in pairs. Although the calculation is done in SU(2) color group it is also valid for SU(3).
