Abstract

11 pp. (1996)., A maximum likelihood analysis of ARGUS data on two-photon production of π + π + π 0 π 0 π − π − is presented. A small fraction of events is due to the production of omega pairs. The γγ → ωω cross section has its maximum value close to threshold.

Abstract

22 pp. (1991)., The reactionγγ→3π+3π- has been studied usig the JADE detector at PETRA. The topological cross sectionσ(γγ→3π+3π-) was measured in the CM energy range 1.5–5.5 GeV. The production ofρ0,s was observed and the average number ofρ0,s per event measured. The contributions of the subprocessesγγ→ρ02π+2π-,γγ→ρ0ρ0π+2π- andγγ→ 3π+3π- (phase space) were studied and 95% C.L. upper limits for the cross sectionσ(γγ→ρ0ρ0π+π- determined. Finally the Bose-Einstein correlation for pairs of like signed pions was observed. A fit to a standard parametrization gave results consistent with other studies of this effect in pion systems.

Abstract

The reaction $e^+e^−→e^+e^−π^0π^0$ has been analyzed using 97pb$^{−1}$ of data taken with the Crystal Ball detector at the DESY $e^−e^+$ storage ring DORIS II at beam energies around 5.3 GeV. For the first time we have measured the cross section for $γγ→π^0π^0$ for π0π0 mvariant masses ranging from threshold to about 2 GeV. We measure an approximately flat cross section of about 10 nb for W=$mπ^0π^0

Abstract

The Crystal Ball detector has been used at the DORIS II storage ring at DESY to study the reaction e+e−→e+e−γ*γ*→e+e−γγ, where X is a narrow resonance with mass between 100 and 3000 MeV. Formation of π0, η, and η’ mesons is observed, and the following meson partial widths are obtained: Γπ0Γ0→γγ=7.7±0.5±0.5 eV, Γη−γγ=0.514±0.017±0.035 keV, and Γη’→γγ=4.7±0.5±0.5 keV. No other narrow resonances are observed, and upper limits are given for the product ΓX→γγBX→γγ. .AE

Abstract

6 pp. (1987)., The final state K$^+K^− \pi^+\pi ^-$ has been studied in γγ interactions using the ARGUS detector at the e+e− storage ring DORIS II at DESY. Production of the vector meson pair K$^{∗0}$(892)K$^{∗0}$(892) is observed for the first time. The cross section for K$^+K^− \pi^+\pi^-$, K$^∗0K^−\pi^+$c.c. and K$^{∗0}$K$^{∗0}$ are all found to be of the order of a few nb. In the W$_{\gamma\gamma}$ range accessible, a mean upper limit of 0.5 n$_b$ at 95% CL is derived for φ$\rho^0$ production.

Abstract

155841 (1980)., The analysis of two photon physics at the e+e− storage ring PETRA is reviewed. Higher order QED processes e+e−→e+e−e+e−(e+e−μ+μ−) have been measured in good agreement with the QED calculations. The production of the f0 resonance has been invstigated and the radiative width has been determined. The total cross section σ(Q2,W) of the inelastic electron photon scattering has been studied in some detail. Evidence for the production of large PT jets in the reaction γγ→qq̄ is reported and a first measurement of the photon structure function in deep inelastic eγ scattering is discussed.

Abstract

113 pp. (1986)., This paper summarizes experimental results on exclusive hadron production in two-photon collisions at electron-positron storage rings and attempts some interpretation. Experimental know-how is described and new suggestions are made for future analyses. New model calculations on resonance form factors and pair production amplitudes are presented. The two-photon vertex is decomposed such that experiments can be parameterized with the minimal number of free parameters. Selection rules for off-shell photon collisions are given in addition to Yang’s theorems.

Abstract

(1982). doi:10.1088/0031-8949/25/1B/011, Selected topics of recent experimental results from the high-energy electron-position storage rings are presented. The topics include some of the τ and charm physics from SPEAR, the upsilon physics from DORIS and CESR, and the γγ physics and quark and gluon physics from the PLUTO and TASSO Collaborations at PETRA. Related data from the JADE and MARK J Collaborations at PETRA are discussed in separate papers at this School.
