Description

We calculate the electromagnetic polarizabilities of the charged and neutral pions and kaons within the framework of a generalized SU(3) Nambu and Jona-Lasinio model. We obtain strong constraints on the results from chiral symmetry. Possible effects of non-linearities in the strange current quark mass are studied. The values obtained for the charged pion electromagnetic polarizabilities are within the error bars of the experimental ones. We predict charged kaon electromagnetic polarizabilities of the order of 10-4 fm3, whereas the ones of the neutral pion and kaon are an order of magnitude smaller
