Inclusive jet production in two-photon collisions at LEP

P. Achard, О. Адриани, M. Aguilar-Benitez, J. Alcaraz Maestre et autres

Inclusive jet production, e + e − → e + e − jet X, is studied using 560 pb −1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The inclusive differential cross section …

Measurement of the cross section of W-boson pair production at LEP

P. Achard, О. Адриани, M. Aguilar-Benítez, J. Alcaraz Maestre et autres

The cross section of W-boson pair-production is measured with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 629.4 pb − 1 , collected at centre-of-mass energies ranging from 189 to 209 GeV, 9834 four-fermion events …

Measurement of the effective weak mixing angle by jet-charge asymmetry in hadronic decays of the Z boson

M. Acciarri, O. Adriani, M. Aguilar-Benítez, S. P. Ahlen et autres

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 asymmetry is measured by means of a …

Search for new physics phenomena in fermion-pair production at LEP

M. Acciarri, O. Adriani, M. Aguilar-Benitez, S. P. Ahlen et autres

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 …

Measurement of W-pair cross sections in e+e− interactions at =172 and W-decay branching fractions

M. Acciarri, O. Adriani, M. Aguilar-Benítez, S. P. Ahlen et autres

We report on the measurement of W-boson pair-production with the L3 detector at LEP at an average centre-of-mass energy of 172.13 GeV. In a data sample corresponding to a total luminosity of 10.25 pb −1 we select 110 four-fermion events with pairs …
