I shall not be able to go into the details of the theory of Kℓ3 form factors [1], but I would like to present a picture of where we stand at present. My emphasis will be on the importance of Kℓ3 form factors in relation to strong interaction symmetries. SU3 has long been recognized as an approximate symmetry group because of the empirical fact that low lying hadronic states fall into SU3 multiplets.
