New measurements of dijet photoproduction at HERA provide information on the gluon density in the photon and on its quark densities at high x γ and high factorisation scales.

The OPAL experiment at LEP has performed a variety of measurements of γγ and eγ scattering at the ee collider LEP to gain a deeper insight into the structure of the photon and its interactions. This review presents a summary of these results.

The studies of Fermi–Dirac correlations of ΛΛ and ¯ Λ ¯ Λ pairs in hadronic Z decays, Bose–Einstein correlations and colour reconnection in W-pairs decays performed by the ALEPH collaboration in e + e − annihilation at LEP are presented. The OPAL analysis of Bose–Einstein correlations in W-pair decays is also discussed.

A review of the decade of Z-pole electroweak physics is presented. Although all experimental work has been completed, it represents a “Golden Age” in our understanding of the Minimal Electroweak Standard Model (MSM). The latest (and nearly final) results from the LEP and SLC experiments are presented. The remaining inconsistencies are discussed and and their effects upon the MSM interpretation ...
