Kaon Polarizabilities in Chiral Perturbation Theory 1

We study the kaon polarizabilities in the framework of Chiral Perturbation Theory to order p4. For the neutral kaon we find that them vanish and they have the first non-zero contribution to order p6. We also emphasize the theoretical potential of an eventual measurement of the kaon polarizabilities, in particular of the neutral kaon ones. PACS numbers: 14.40.Aq, 13.40.Gp, 13.60.Fz, 12.39.Fe
