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 Branching Fractions of $\tau$ Hadronic Decays / L3 Collaboration
Using data collected with the L3 detector at LEP at the Z peak, the branching fractions of the $\tau$ lepton into the hadronic final states, $h^- n\pi^0 \nu(n=0,1,2, >= 3)$ and $h^-h^+h^- n\pi^0 \nu$ where $h^\pm$ denotes a charged hadron, are measured to be .....

Study of resonance formation in the mass region 1400 - 1500 MeV through the reaction $\gamma\gamma \to K^{0}_{S} K^{\pm} \pi^{\mp}$ / L3 Collaboration
The K^0_SK^+-\pi-+ final state in two-photon collisions is studied with the L3 detector at LEP at e+e- centre-of-mass energies from 183 to 209 GeV with an integrated luminosity of 664.6 pb-1. The \eta(1475) and f1(1420) mesons are observed and their contribution is separated by measuring the formation rates as a function of the photon virtuality Q2. [...]

Search for Exclusive B Decays to J and $\eta$ or $\pi^{0}$ with the L3 Detector / L3 Collaboration
A search for exclusive decays of $\ensuremath{\mathrm{B_d^0}}$ and $\ensuremath{\mathrm{B_s^0}}$ mesons has been performed in the channels $\ensuremath{\mathrm{B_d^0}\rightarrow\mathrm{J}\eta}$,\,\, $\ensuremath{\mathrm{B_s^0}\rightarrow\mathrm{J}\eta}$,\,\, $\ensuremath{\mathrm{B_d^0}\rightarrow\mathrm{J}\pi^0}$ and $\ensuremath{\mathrm{B_s^0}\rightarrow\mathrm{J}\pi^0}$. The data sample consisted of more than three and half million hadronic $\ensuremath{\mathrm {Z}}$ decays collected by the L3 experiment at LEP from 1991 through 1995 [...]

Measurement of $\eta '(958)$ formation in two-photon collisions at LEP1 / L3 Collaboration
The formation of the eta' in the reaction ee->ee eta'->ee pi pi gamma has been measured by the L3 detector at a centre-of-mass energy of 91 GeV. The radiative width of the eta' has been found to be 4.17 +/- 0.10(stat.) +/- 0.27(sys.) keV . [...]

$\Upsilon$ production in Z Decays / L3 Collaboration
We have searched for evidence of Upsilon production in 3.5 million hadronic Z decays collected by the L3 detector at LEP in 1991-1995. No signals are observed for the decay chain Z -> Upsilon X; Upsilon -> l+l- (l= e, mu), therefore upper limits at the 95% confidence level are set on the following Z branching fractions: BR (Z -> Upsilon(1S) X) < 5.5 x 10**-5; BR (Z -> Upsilon(2S) X) < 13.9 x 10**-5; BR (Z -> Upsilon(3S) X) < 9.4 x 10**-5..

$K^{0}_{S}$ and $\Lambda$ production in quark and gluon jets at LEP / L3 Collaboration
A measurement of the $\mathrm{K^0_s}$ and $\Lambda$ inclusive production rates and momentum spectra in two- and three-jet events is presented. On the basis of about 3.1~million Z decays collected with the L3 detector at LEP, we observe that the production of these particles is well modeled by string fragmentation..
