Measurement of the photon structure function F2 ψ at Q2 from 7 to 70 (GeV/c)2
Zeitschrift für Physik C Particles and Fields 31:4 (1986) 527-535
Abstract:
We have measured the process e+e-→e+e-+hadrons, where one of the scattered electrons was detected at large angles, with Q2 ranging from 7 to 70 (VeV/c)2. The photon structure function F2γ(x, Q2) was determined at an average Q2 of 23 (GeV/c)2. The measurements were compared to theoretical predictions of the Quark Parton Model and Quantum Chromodynamics. In both models a hadronic part was added. Within the errors the data are in agreement with the QPM using quark masses of 300 MeV/c2 for the light quarks. The data also agree with a QCD calculation including higher order corrections. A fit yielded a {Mathematical expression} value of 140-65+190 MeV, where the errors include statistical and systematic uncertainties. © 1986 Springer-Verlag.Measurement of the radiative width of the A2 (1320) in two-photon interactions

Abstract:
The reaction e+e-→e+e- A2 (1320) has been observed by detecting the decay A2→π+,π-π0. The two-photon width of the A2 has been measured to be G{cyrillic}(A2→γγ)=(0.09±0.27 (stat)±0.16 (syst)) keV. The cross section σ(γγ→π+,π-π0 has been determined outside the A2 resonance region. © 1986 Springer-Verlag.Composition of particles emitted at largepT and medium angles inpp, dd, andαα collisions at the CERN intersecting storage rings
