New results on convergence of hydrodynamic gradient expansion
Relativistic hydrodynamics, viewed as an effective field theory, is formulated in a derivative expansion. Studies of applicability of relativistic hydrodynamics in nuclear collisions at RHIC and LHC prompted the question about convergence properties of this expansion. I will discuss new developments on this topic that, for the first time, allow to make definite statements about the convergence of hydrodynamic gradient expansion. Based on arXiv:2007.05524 [hep-th] and on ongoing work.
