Charmed quark component of the photon wave function

We determine the cc-bar component of the photon wave function on the basis of (i) the data on the transitions e{sup +}e{sup -} {yields} J/{psi}(3096), {psi}(3686), {psi}(4040), {psi}(4415), (ii) partial widths of the two-photon decays {eta}{sub c0}(2979), {chi}{sub c0}(3415), {chi}{sub c2}(3556) {yi...
