The total cross section γγ->hadrons

Creators

Description

Measurements of the total cross section for γγ-> hadrons are presented. There are new results from double-tagging (P2not=0, Q2not=0), single tagging (P2approx.=0, Q2not=0), and no-tagging (P2approx.=0, Q2approx.=0n experiments at e+e- storage rings. The measurements cover a Q2 range from 0 to 100 GeV2, and a W range from 2 to 20 GeV. The significance of these data for the interpretation of the photon as a set of vector mesons (VDM) and as an electromagnetic field quantum coupling to point-like quarks (QPM) is discussed. (orig.)
