Photon structure functions and azimuthal correlations of lepton pairs in tagged $\gamma\gamma$ collisions / L3 Collaboration
Measurements of the QED structure of the photon based on the reaction ee to ee gamma /sup (*)/(P/sup 2/) gamma *(Q/sup 2/) to ee mu mu are discussed. This review is an update of the discussion of the results on the QED structure of the photon and covers the published measurements of the photon structure functions F/sub 2//sup gamma /, F/sub A//sup gamma / and F/sub B//sup gamma / and of the differential cross-section d sigma /dx for the exchange of two virtual photons.

Measurement of the effective weak mixing angle by jet-charge asymmetry in hadronic decays of the Z boson / L3 Collaboration
The coupling of the Z boson to quarks is studied in a sample of about 3.5 million hadronic Z decays collected by the L3 experiment at LEP from 1991 to 1995. The forward-backward quark charge asymmet ry is measured by means of a jet charge technique [...]

Upper limit on the lifetime difference of short- and long-lived $B^0_s$ mesons / L3 Collaboration
An upper limit on the lifetime difference of short- and long-lived $\rm B^0_s$ mesons has been obtained using an inclusive bottom hadron sample from 2 million hadronic Z decays collected by the L3 experiment at LEP. A lifetime fit has been performed on data samples separately enriched in neutral and charged b hadrons. [...]

Measurement of the Michel parameters and the average $\tau$-neutrino helicity from $\tau$ decays at LEP / L3 Collaboration
Four of the Michel parameters and the average tau-neutrino helicity have been measured by analysing tau decay spectra in 147 \pb ~of data collected by the L3 detector. The decays \tte, ~\ttm, ~\ttp, ~\ttr ~and their charge conjugates were considered. [...]

Test of CP invariance in $Z \to \mu^+ \mu^- \gamma$ decay / L3 Collaboration
We report on the first test of CP invariance in Z decays with hard photon radiation. The data recorded with the L3 detector at centre-of-mass energies near the Z resonance are used to search for CP violation in the reaction $\mathrm{e^+e^-}\rightarrow\mu^+\mu^-\gam ma$. [...]
