Abstract

It is shown how the tensor gravity makes the electromagnetic mass splitting of pions finite without using any lagrangian model for the strong interaction. The mass splitting is sensitive to the spectral-function sum rules. A finite mass splitting does not lead to a unique modification of the second Weinberg sum rule. For the electromagnetic mass difference of pions good values are obtained by suitably chosen input data.
