Abstract: (Elsevier)
In ultrarelativistic plasmas, the existence of unscreened magnetic interactions and the presence of massless particles strongly affect the properties of the quasiparticles and of the collective modes. In this note, I discuss the peculiar splitting of the fermion dispersion relation at low momentum, which exhibits features of a collective phenomenon. I then show how the unscreened soft magnetic interactions affect the lifetime of quasiparticles.- plasma: relativistic
