Search for new physics phenomena in fermion-pair production at LEP / L3 Collaboration
The measurements of hadron and lepton--pair production cross sections and lepton--pair forward--backward asymmetries performed with the L3 detector at centre--of--mass energies between 130 GeV and 172 GeV are used to search for new physics phenomena. New physics effects involving four fermion vertices -- contact interactions -- are looked for in all channels. [...]

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.

Determination of the number of light neutrino species from single photon production at LEP / L3 Collaboration
A determination of the number of light neutrino families performed by measuring the cross section of single photon production in \ee\ collision near the \Zo\ resonance is reported. From an integrated luminosity of $100~\mathrm{pb^{-1}}$, collected during the years 1991--94, we have observed 2091 single photon candidates with an energy above 1~\GeV\ in the polar angular region $45^\circ < \theta_\gamma < 135^\circ$ [...]

Measurement of the $B_{d}^{0} - \overline{B}_{d}^{0}$ oscillation frequency / L3 Collaboration
Time-dependent ${\mathrm{B^{0}}\mbox{-}\bar{\mathrm{B}} ^{0}}$ mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used [...]

Angular multiplicity fluctuations in hadronic Z decays and comparison to QCD models and analytical calculations / L3 Collaboration
Local multiplicity fluctuations in angular phase space intervals are studied using factorial moments measured in hadronic events at $\sqrt{s}\simeq 91.2\GeV$, which were collected by the L3 detector at LEP in 1994. Parton shower Monte Carlo programs agree well with the data. [...]

Measurement of the Weak Dipole Moments of the $\tau$ Lepton / L3 Collaboration
Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the $\Zo$ mass, a measurement of the weak anomalous magnetic dipole moment, $a^w_{\tau}$,~ and of the weak electric dipole moment, $d^w_{\tau}$, of the $\tau$ lepton is performed. These quantities are obtained from angular distributions in $e^{+}e^{-}\rightarrow\tau^{+}\tau^{-} \rightarrow h^{+} \bar{\nu}_{\tau} h^{-} \nu_{\tau}$, where $h$ is a $\pi$ or a $\rho$. [...]

Local multiplicity fluctuations in hadronic Z decay / L3 Collaboration
Local multiplicity fluctuations in hadronic Z decays are studied using the L3 detector at LEP. Bunching parameters are used for the first time in addition to the normalised factorial moment method. [...]

Search for scalar leptons, charginos and neutralinos in $e^{+} e^{-}$ collisions at $\sqrt{s}$ = 161-172 GeV / L3 Collaboration
Scalar leptons, charginos and neutralinos, predicted by supersymmetric theories, have been searched for in data samples collected with the L3 detector at centre-of-mass energies of 161 GeV and 172 GeV with integrated luminosities of 10.7 pb$^{-1}$ and 10.0 pb$^{-1}$ respectively. No evidence for such particles is found. [...]

Measurement of the average lifetime of b-hadrons in Z decays / L3 Collaboration
We present a measurement of the average b-hadron lifetime ${\rm \tau_b}$ at the $\mathrm{e^+e^-} \, $ collider LEP. Using hadronic Z decays collected in the period from 1991 to 1994, two independent analyses have been performed [...]
