Search for new physics in energetic single photon production in e+e− annihilation at the Z resonance

M. Acciarri, О. Адриани, M. Aguilar-Benı́tez, S. P. Ahlen et autres

Using a sample of e+e− annihilation events collected with the L3 detector at the Z resonance corresponding to an integrated luminosity of 137 pb−1, we have searched for anomalous production of γX final states where X represents stable, weakly interacting particles and …

Production of e, μ and τ pairs in untagged two-photon collisions at LEP

M. Acciarri, О. Адриани, M. Aguilar-Benitez, S. P. Ahlen et autres

The two-photon collision reaction e + e − → e + e − l + l − has been studied at 2 ≈91 GeV using the L3 detector at LEP for l = e, μ , τ . We have analysed untagged …

Measurement of D-s(-)->tau(-)(nu)over-bar(tau) and a new limit for B-->tau(-)(nu)over-bar(tau center dot)

M. Acciarri et al., M. AguilarBenitez, S. Ahlen, B. Alpat et autres

Using a data sample of 1475000 Z --> q (q) over bar(gamma) events collected during 1993 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, D-s(-) --> tau(-)(v) over bar(tau) and B- --> tau(-)(v) …

Measurement of muon-pair production at 50GeV<root s<86GeV at LEP

M. Acciarri et al., A. Adam, M. AguilarBenitez, S. Ahlen et autres

Using the data recorded with the L3 detector at LEP, we study the process e(+)e(-) --> mu(+)mu(-)(gamma) for events with hard initial-slate photon radiation. The effective centre-of-mass energies of the muons range from 50 GeV to 86 GeV. The data sample corresponds …
