Total hadronic cross-section of photon-photon interactions at OPAL / Wäckerle, F (Fakultät für Phys, Freiburg Univ)
The total hadronic cross-section sigma /sub gamma gamma / for the interaction of real photons, gamma gamma to hadrons, is extracted from a measurement of the cross-section of the process e/sup +/e/sup -/ to e/sup +/e/sup -/ gamma * gamma * to e/sup +/e/sup -/+hadrons using a luminosity function for the photon flux and form factors for extrapolating to Q/sup 2/=0. The data was taken with the OPAL detector at LEP at e/sup +/e/sup -/ centre-of-mass energies square root (s/sub ee/)=161 GeV, 172 GeV and 183 GeV. [...]

Production of D* mesons in photon-photon collisions at $\sqrt{s}_{ee}$ = 183 GeV and 189 GeV using the OPAL detector at LEP / Patt, J (Fakultät für Phys, Freiburg Univ)
The inclusive production of D*/sup +or-/ mesons in photon-photon collisions has been measured using the OPAL detector at LEP at e/sup +/e/sup -/ centre-of-mass energies square root (s/sub ee/) of 183 and 189 GeV. The D*/sup +/ mesons are reconstructed in their decay to D /sup 0/ pi /sup +/ with the D/sup 0/ observed in the two decay modes K/sup -/ pi /sup +/ and K/sup -/ pi /sup +/ pi /sup -/ pi /sup +/.

Total cross-section and diffractive $\rho^{0}$ production in $\gamma\gamma$ collisions at L3 / Csilling, Akos (CERN) /L3 Collaboration
The reaction e/sup +/e/sup -/ to e/sup +/e/sup -/ gamma * gamma * to e/sup +/e/sup -/hadrons is analysed for quasi-real virtual photons using data collected by the L3 detector during the LEP high energy runs at square root (s)=183 and 189 GeV. Preliminary results on the cross sections sigma (e/sup +/e/sup -/ to e/sup +/e/sup -/hadrons) and sigma ( gamma gamma to hadrons) are given in the interval 5 Ge V<or=W/sub gamma gamma /<or=145 GeV.

How asymptotic freedom predictions for R= sigma (e/sup +/e/sup -/ to hadrons)/ sigma (e/sup +/e/sup -/ to mu /sup +/ mu /sup -/) lead to a paradox / Schierholz, G ; Schmidt, M G
Describing the total cross-section via the one-hadron inclusive distribution e/sup +/e/sup -/ to h+X, one is led into a contradiction to the asymptotic freedom (naive quark-parton model) result R= Sigma Q /sub i//sup 2/. (12 refs)..

Measurement of the cross-section of single W boson production and the anomalous couplings in the L3 experiment / Yang Min ; Chen Guo Ming ; Yang Hai Jun ; Xiong Zhao Hua ; Lü Yu Sheng ; Chen He Sheng
In this paper, the cross-sections of single W boson production in e /sup +/e/sup -/ to e/sup -/ nu /sub e/W/sup +/ and e/sup +/e/sup -/ to e/sup +/ nu /sub e/W/sup -/ were measured based on the data samples collected by the L3 detector in 1996 and 1997. The limits on the anomalous couplings of the WW gamma triple gauge bosons are derived at 95% CL:-0.65< Delta kappa /sub gamma /<0.82 and -1.37< lambda /sub gamma /<0.92. [...]

The hadronic structure of $\gamma^{*}\gamma^{*}$ interactions at LEP / Surrow, B (CERN)
The hadronic structure of gamma /sup */ gamma /sup */ interactions has been investigated at the e/sup +/e/sup -/ collider LEP by the L3 and OPAL collaborations. Recent results on measurements of the hadronic gamma /sup */ gamma /sup */ cross-section and the effective virtual photon structure function F/sub eff//sup gamma / are presented in comparison to theoretical predictions.

Cross section measurement of $\tau$ pairs in two photon collisions with the L3 detector at LEP 2 / Haas, D (Basel U.)
The production of tau pairs in gamma gamma collisions is studied with the L3 detector at LEP. Data were collected at square root =189-202 GeV for a total integrated luminosity of 393.0 pb/sup -1/. [...]

Multiphoton production and tests of QED at LEP-II / Winter, M (IReS, Univ Louis Pasteur, Strasbourg, France)
Data collected by the 4 LEP collaborations from 1995 to 2000 at collision energies ranging from 130 to 208 GeV were used to measure the cross-section of the process e/sup +/e/sup -/ to gamma gamma ( gamma ). QED predictions for this reaction were tested with a few per-cent accuracy and manifestations of physics beyond the standard model (SM) were investigated. [...]

Measurement of the Compton scattering process $e\gamma \to eZ/\gamma^{*}$ at LEP2 / Maier-Metz, H (CERN) /OPAL Collaboration
The process e gamma to eZ/ gamma * is studied in e/sup +/e/sup -/ collisions with the OPAL detector at LEP at a centre of mass energy of square root (s)=189 GeV. The cross-section times the branching ratio of the Z/ gamma * decaying into hadrons is measured within Lorentz invariant kinematic limits to be (4.6+or-0.9+or-0.6) pb for hadronic masses between 5 GeV and 60 GeV and (1.5+or-0.3+or-0.3) pb for hadronic masses above 60 GeV.

$O\alpha_{s}^{3}$ estimate for the longitudinal cross-section in $e^{+}e^{-}$ annihilation to hadrons / Chishtie, F A
Using renormalization group (RG) and Pade approximant methods, we estimate the O( alpha /sub s//sup 3/) contribution to the longitudinal cross-section ( sigma /sub L/) in the e/sup +/e/sup -/ annihilation to hadrons. The O( alpha /sub s//sup 3/) contribution is expressed as a quadratic polynomial in L identical to l( mu /sup 2//Q /sup 2/). [...]
