A general technique for obtaining dispersion relations in the mass variable is proposed. The method is used in order to translate the low-energy theorems valid for "mathematical pions" of zero four-momentum into physically meaningful expressions for real pions. Our procedure is explicitly applied to

We consider the coupling between collective and intrinsic degrees of freedom of a many-dimensional quantum system. We give a criterion for the validity of the adiabatic approximation in tunneling processes and derive an equation for the "lag" of the intrinsic wave function with respect to the adiaba
