Midrapidity antiproton-to-proton ratio in pp collisions at $\sqrt{s} = 0.9$ and $7$~TeV measured by the ALICE experiment / ALICE collaboration
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at $\sqrt{s} = 0.9$ and $7$~TeV during the initial running periods of the Large Hadron Collider(LHC). The measurement covers the transverse momentum interval $0.45 < p_{\rm{t}} < 1.05$~GeV/$c$ and rapidity $|y| < 0.5$. [...]

Higgs Candidates in $e^{+}e^{-}$ Interactions at $\sqrt{s}$ = 206.6 GeV / L3 Collaboration
In a search for the Standard Model Higgs boson, carried out on 212.5 pb-1 of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5 pb-1 above root(s) = 206GeV, an excess of candidates for the process e+e- -> Z* -> HZ is found for Higgs masses near 114.5GeV. We present an analysis of our data and the characteristics of our strongest candidates..

Search for Heavy Neutral and Charged Leptons in $e^+ e^-$ Annihilation at LEP / L3 Collaboration
A search for exotic unstable neutral and charged heavy leptons as well as for stable charged heavy leptons is performed with the L3 detector at LEP. Sequential, vector and mirror natures of heavy leptons are considered. [...]

Measurement of Bose-Einstein Correlations in $e^{+}e^{-}\to W^{+}W^{-}$ Events at LEP / L3 Collaboration
Bose-Einstein correlations in W-pair production at LEP are investigated in a data sample of 629 pb$^{-1}$ collected by the L3 detector at $\sqrt{s}=$ 189--209\,GeV. Bose-Einstein correlations between pions within a W decay are observed and found to be in good agreement with those in light-quark Z decay. [...]

Measurement of Genuine Three-Particle Bose-Einstein Correlations in Hadronic Z decay / L3 Collaboration
We measure three-particle Bose-Einstein correlations in hadronic Z decay with the L3 detector at LEP. Genuine three-particle Bose-Einstein correlations are observed. [...]

Search for R-parity Violating Decays of Supersymmetric Particles in $e^+ e^-$ Collisions at LEP / L3 Collaboration
A search, in $e^+ e^-$ collisions, for chargino, neutralino, scalar lepton and scalar quark pair-production is performed, without assuming R-parity conservation in decays, in the case that only one of the coupling constants $\lambda_{ijk}$ or $\lambda''_{ ijk}$ is non-negligible. No signal is found in data up to a centre-of-mass energy of 208 \GeV. [...]

Search for Scalar Leptons and Scalar Quarks at LEP / L3 Collaboration
Scalar partners of quarks and leptons, predicted in supersymmetric models, are searched for in e^+e^- collisions at centre-of-mass energies between 192GeV and 209GeV at LEP. No evidence for any such particle is found in a data sample of 450 pb^-1. [...]

Search for Colour Singlet and Colour Reconnection Effects in Hadronic Z Decays at LEP / L3 Collaboration
A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of particles are found to be sensitive indicators of such effects. [...]

Study of the $e^{+}e^{-}\to Ze^{+}e^{-}$ Process at LEP / L3 Collaboration
The cross section of the process $\rm e^+e^-\rightarrow Ze^+e^-$ is measured with ~0.7\,fb$^{-1}$ of data collected with the L3 detector at LEP. Decays of the Z boson into quarks and muons are considered at centre-of-mass energies ranging from $183$ GeV up to $209$ GeV. [...]

Study of Spin and Decay-Plane Correlations of W Bosons in the $e^{+} e^{-} \to W^{+} W^{-}$ Process at LEP / L3 Collaboration
Data collected at LEP at centre-of-mass energies \sqrt(s) = 189 - 209 GeV are used to study correlations of the spin of W bosons using e+e- -> W+W- -> lnqq~ events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. [...]
