Open full text 14 citations

Abstract

In addition to the vector meson poles in the form factors of charged pions and kaons additional intrinsic form factors of pions and kaons are found. A detailed study of the form factors of pions and kaons in both timelike and spacelike regions is presented. Theory agrees well with data up to $q\ensuremath{\sim}1.4$ GeV. In this study there is no adjustable parameter.
