Abstract:
We consider time dependent correlation functions of non-abelian gauge fields at finite temperature. An effective theory for the soft () field modes is derived by integrating out the field modes with momenta of order and of order in a leading logarithmic approximation. In this effective theory the time evolution of the soft fields is determined by a local Langevin-type equation. As an application, the rate for hot electroweak baryon number violation is estimated as . Furthermore, possible consequences for non-perturbative lattice computations of unequal time correlation functions are discussed.Note:
