Dynamics of particle production by strong electric fields in non-Abelian plasmas
John F. Dawson, Bogdan Mihaila, Fred Cooper
We develop methods for computing the dynamics of fermion pair production by strong color electric fields using the semi-classical Boltzmann-Vlasov equation. We present numerical re…
