Measurement of the Probability of Gluon Splitting into Charmed Quarks in Hadronic Z Decays
L3 Collaboration
We have measured the probability, n(g->cc~), of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods…
Search for Extra Dimensions in Boson and Fermion Pair Production in e+e- Interactions at LEP
L3 Collaboration
Extra spatial dimensions are proposed by recent theories that postulate the scale of gravity to be of the same order as the electroweak scale. A sizeable interaction between gravit…
Single and Multi-Photon Events with Missing Energy in e+e- Collisions at \sqrt{s} = 189 GeV
L3 Collaboration
Single and multi-photon events with missing energy are analysed using data collected with the L3 detector at LEP at a centre-of-mass energy of 189 GeV, for a total of 176 pb^{-1} o…
Measurement of Triple-Gauge-Boson Couplings of the W Boson at LEP
L3 Collaboration
We report on measurements of the triple-gauge-boson couplings of the W boson in e+e- collisions with the L3 detector at LEP. W-pair, single-W and single-photon events are analysed…
Search for Charginos and Neutralinos in e+e- collisions at \sqrt{s} = 189 Gev
L3 Collaboration
We report the result of a search for charginos and neutralinos, in e+e- collisions at 189 GeV centre-of-mass energy at LEP. No evidence for such particles is found in a data sample…
Search for Charged Higgs Bosons in e+e- Collisions at \sqrt{s} = 189 GeV
L3 Collaboration
A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at a centre-of-mass energy of 188.6 GeV, corresponding to an integrate…
