Phys. Rev. Lett. 70, 2363–2366 (1993)Non-Abelian Boltzmann equation for mixing and decoherenceSee Also: Erratum Received 24 August 1992; published in the issue dated 19 April 1993 We consider particle oscillations and their damping in second-quantized form. We find that the damping or ‘‘decoherence’’ may be described by a Boltzmann-like collision integral with ‘‘non-Abelian blocking factors’’ (fermions). Earlier results are generalized in that the momentum degrees of freedom are included and that the mixing equations become intrinsically nonlinear at high densities. © 1993 The American Physical Society URL:
