| Abstract | Electric (α) and magnetic (β) polarizabilities characterize the global deformation response of a composite system in static uniform external electric and magnetic fields. They provide precious information about the underlying dynamics of the composite system. As a result, a precise measurement of the pion polarizabilities is of great importance to understand the inner structure of the pion. Chiral symmetry allows one to predict the electromagnetic polarizabilities of charged pion in terms of the radiative decay π → eνeγ [1] , |
