The L3 experiment is one of the six large detectors designed for the new generation of
electron-positron accelerators. It is the only detector that concentrates its efforts on limited goals of …

The structure of hadronic events fromZ 0 decay is studied by measuring event shape variables,
factorial moments, and the energy flow distribution. The distributions, after correction for …

We report on the measurement of the leptonic and hadronic cross sections and leptonic
forward-backward asymmetries at theZ peak with the L3 detector at LEP. The total luminosity of …

We report the results of first physics runs of the L3 detector at LEP. Based on 2538 hadron
events, we determined the mass m z 0 and the width Γ z 0 of the intermediate vector boson Z 0 …

In this report we summarize the major results from the first three years of running of the L3
detector at the Large Electron Positron collider (LEP). The L3 detector was designed to …

We present a measurement of the photon structure functionF 2 γ in the reactionee→eeX forQ
2 in the range 0.2<Q 2 <7 GeV 2 , using 9,200 multihadron events obtained with the TPC/…

We have studied the reactionse + e − →hadrons,e + e − , μ + μ − and τ + τ − , in the energy
range 88.2 $$ \leqq \sqrt s \leqq 94.2$$ GeV. A total luminosity of 5.5 pb −1 , corresponding to …

We report measurements of π±K±, and p, p inclusive cross sections and fractions in e+ e−
annihilation at s= 29 GeV, for the momentum interval 0.01< z= pp beam< 0.90. The analysis is …

The formation of the η′ in the reaction e + e − →e + e − η′→e + e − π + π − γ has been
measured by the L3 detector at a centre-of-mass energy of 91GeV . The radiative width of the η…

We search for neutral heavy leptons that are isosinglets under the standard SU (2) L gauge
group. Such neutral heavy leptons are expected in many extensions of the standard model. …
