Multi-photon production in e + e − collisions at √ s = 189 GeV The OPAL Collaboration

K. Ackerstaff, +264 more
TL;DR: In this article , the process e + e − → γγ ( γ ) is studied using data recorded with the OPAL detector at LEP, where the data sample taken at a centre-of-mass energy of 189 GeV corresponds to a total integrated luminosity of 178 pb − 1 .

Georges Aad, +2898 more
TL;DR: A measurement of jet shapes in top-quark pair events using 1.8 fb−1 collision data recorded by the ATLAS detector at the LHC is presented in this article.

NP triple scattering experiments and I=O NN phase shifts

TL;DR: In this paper, the Wolfenstein parameters Dt, Rt and At have been measured in free np elastic scattering with an accuracy of ± 0.05 at 220, 325, 425 and 495 MeV in the center of mass angular range 60° to 160°.

Upper limit on theν τ mass fromτ → 3hν τ decays

Gideon Alexander, +348 more
TL;DR: In this article, a new technique has been used to determine a limit on theντ mass using Z0→τ+τ− events selected from 140 pb−1 of data collected with the OPAL detector at LEP during the period 1990-1994.
