On the stability of Yang-Mills vacuum
The (anti)self-dual covariantly constant vacuum fields have positive/stable and infinitely many zero modes, so called Leutwyller chromons. A regularisation method is suggested that allows to sum the contribution of the zero modes and to obtain the effective Lagrangian that has contribution of all po...
