Abstract
The electromagnetic and weak structure functions of the photon can be studi ed in the deep inelastic electron-photon processes e gamma --> e + X and e gamma --> nu + X. While at low energies only virtual photon exchange is ope rative in the neutral-current process, additional Z-exchange becomes releva nt for high Q(2) of order M-Z(2) at e(+)e(-) linear colliders. Likewise the charged-current process can be observed at these high energy colliders. By measuring the electroweak neutral- and charged-current structure functions , the up- and down-type quark content of the photon can be determined separ ately. (C) 1999 Elsevier Science B.V.
