PHOTON-PHOTON INTERACTIONS

Recent results in γγ physics are presented. They include a number of new measurements of the γγ widths of members of the J PC = 0 −+ and 2 ++ SU(3) nonets, a search for 0 -+ radial excitations, studies of low mass ππ production and new results in the measurements of exclusive β c and inclusive D∗ ± production. Formation of spin=1 resonances in tagged γγ∗ scattering is described as well as new results in vector meson pair production. Finally new results on the measurement of the photon structure function F 2 γ are reported.
