TL;DR: In this article, single top production in e^+e^- annihilations is searched for in data collected by the L3 detector at centre-of-mass energies from 189 to 209 GeV, corresponding to a total integrated luminosity of 634 pb-1.

TL;DR: In this paper, the ηπ + π − final state in two-photon collisions was studied with the L3 detector at LEP, at centre-of-mass energies from 183 to 209 −GeV with an integrated luminosity of 664.6 −1.

TL;DR: In this paper, a search for chargino, neutralino, scalar lepton and scalar quark pair-production in e+e− collisions is performed, without assuming R-parity conservation in decays, in the case that only one of the coupling constants is non-negligible.

TL;DR: In this article, the authors studied the process e+e−−→W+W−γ using the data collected by the L3 detector at LEP and obtained an integrated luminosity of 427.4 pb−1 at center-of-mass energies from 192 to 207 GeV.

TL;DR: In this article, the structure of high energy hadronic events recorded by the L3 detector at s ⩾192 ǫGeV was studied and the distributions of several event shape variables were compared to resummed O(α s 2 ) QCD calculations.

TL;DR: Bose-Einstein correlations in W-pair production at LEP were investigated in a data sample of 629 pb−1 collected by the L3 detector at s =189 −209 −GeV as mentioned in this paper.

TL;DR: In this paper, double-tag events in two-photon collisions are studied using the L3 detector at LEP centre-of-mass energies from root(s)=189 GeV to 209 GeV.

TL;DR: In this paper, a Higgs particle produced in association with a Z boson and decaying into two photons is searched for in the data collected by the L3 experiment at LEP, but no signal is observed in 447.5 pb^-1 of data recorded at centre-of-mass energies up to 209 GeV.

TL;DR: Bose-Einstein correlations of both neutral and like-sign charged pion pairs are measured in a sample of 2 million hadronic Z decays collected with the L3 detector at LEP as discussed by the authors.

TL;DR: In this article, the cross section of the process e + e − → Z γ γ → q q ¯ γ − γ is measured with 215 pb−1 of data collected with the L3 detector during the final LEP run at centre-of-mass energies around 205 GeV and 207 GeV.

TL;DR: In this article, single W boson production in electron-positron collisions was studied with the L3 detector at centre-of-mass energies between 192 and 209 GeV.

TL;DR: In this paper, three-particle Bose-Einstein correlations in hadronic Z decay with the L3 detector at LEP were measured and compared by comparing two-and threeparticle correlations, and they found that the data are consistent with fully incoherent pion production.

TL;DR: In this paper, the L3 detector at LEP has been used to study the rare baryon pair production in two-photon collisions with an integrated luminosity of 844 pb-1.

TL;DR: In this paper, a search for the lightest CP-even and neutral CP-odd Higgs bosons of the minimal supersymmetric standard model is performed using 216.6 poly(n)pb−1 of data collected with the L3 detector at LEP at center-of-mass energies between 203 and 209.

TL;DR: In this paper, the authors studied the process e+ e- -> n gamma with n = 2 at centre-of-mass energies ranging from −1 to 208 GeV, and the total and differential cross sections were found to be in agreement with the QED expectations.

TL;DR: In this article, the authors measured differential cross sections as a function of the particle transverse momentum and pseudo-rapidity and compared the results to Monte Carlo predictions and to NLO QCD calculations.

TL;DR: In this paper, the L3 detector at LEP was used to study D^{*+-} production in two-photon collisions, using 683 pb^{-1} of data collected at centre-of-mass energies from 183 to 208 GeV.
