Abstract
Transport coefficeints, in particular the shear viscosity to entropy density ratio is studied in systems where the small-width quasiparticle assumption is not valid. It is found that has no unversal lower bound, the minimal value depends on the system and the temperature, and can be even zero. We construct models where the conjectured bound is violated.
