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 $\mathrm{e^+e^-}\rightarrow\mu^+\mu^-\gam ma$. [...]

Study of the hadronic photon structure function $F^\gamma_2$ at LEP / L3 Collaboration
The hadronic photon structure function $F^\gamma_2$ is studied in the reaction $\mathrm{e^+e^-} \rightarrow \mathrm{e^+e^-hadrons}$ at LEP with the L3 detector. The data, collected from 1991 to 1995 at a centre-of-mass energy $\sqrt{s} \simeq 91 \GeV$, correspond to an integrated luminosity of 140~pb$^{-1}$. [...]

Measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons and a determination of |$V_{ub}$| at LEP / L3 Collaboration
A measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons, $\mathrm{b}\rightarrow\mathrm{X}_\mathrm{u }\ell\nu$, has been performed using almost two million hadronic Z decays collected by the L3 experiment at LEP, yielding the result: \begin{displaymath} \mathrm{Br}(\mathrm{b}\rightarrow\mathrm{X}_\mathr m{u}\ell\nu) = (3.3 \pm 1.0 \pm 1.7)\times 10^{-3}. \end{displaymath} The first uncertainty is statistical and the second is systematic.

Tests of the charged weak current in correlated hadronic $\tau$ decays using L3 at LEP / Gerald, J
With a sample of 86,000 Z -> t + t - (y) events collected with the L3 detector at LEP in 1991, 1992, and 1993, we have measured the hadronic chirality parameter ( h ) using a subsample of 22,500 events with a pi and/or p in the final state [...]

Measurement of $\tau$ polarisation at LEP / L3 Collaboration
Using the data collected with the L3 detector at LEP between 1990 and 1995, corresponding to an integrated luminosity of 149 pb$^{-1}$, the $\tau$ longitudinal polarisation has been measured as a function of the production polar angle using the $\tau$ decays \thad\ ($\rm h = \pi, \rho, \aone$) and \tlep\ ($\rm \ell = e, \mu$). From this measurement the quantities æl~and \at, which depend on the couplings of the electron and the $\tau$ to the Z, are determined to be $\ael = 0.1678 \pm 0.0127 \pm 0.0030 $ and $\at = 0.1476 \pm 0.0088 \pm 0.0062$, consistent with the hypothesis of e--$\tau$ universality.
