Measurement of the Q2 evolution of the photon structure function Fγ2

K. Ackerstaff, +360 more
- 16 Oct 1997 - 
TL;DR: In this paper, the photon structure function F 2 γ (x, Q 2 ) at four values of Q 2 between 9 and 59 GeV 2 was measured with the OPAL detector at centre-of-mass energies of 161-172 GeV, with a total integrated luminosity of 18.1 pb −1.
Journal ArticleDOI

Measurement of the Hadronic Cross-Section for the Scattering of Two Virtual Photons at LEP

Giovanni Abbiendi, +312 more
TL;DR: In this paper, the interaction of virtual photons is investigated using the reaction of virtual hadrons based on data taken by the OPAL experiment at the center-of-mass energies of the virtual photons.
Journal ArticleDOI

Search for flavour-changing neutral current top-quark decays to qZ in pp collision data collected with the ATLAS detector at √s = 8 TeV

Georges Aad, +2847 more
TL;DR: In this paper, a search for the flavour-changing neutral-current decay was performed using data collected by the ATLAS detector during 2012 from proton-proton collisions at the Large Hadron Collider at a center-of-mass energy of root s = 8 TeV, corresponding to an integrated luminosity of 20.3 fb(-1).
Journal ArticleDOI

Measurement of |V(cb)| using B̄0 → D*+l-ν̄ decays

Giovanni Abbiendi, +334 more
- 01 Mar 1997 - 
TL;DR: In this article, the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element Vcb has been measured using B0→D∗+l−ν decays recorded on the Z0 peak using the OPAL detector at LEP.
Journal ArticleDOI

Measurements of top quark spin observables in tt¯ events using dilepton final states in √s = 8 TeV pp collisions with the ATLAS detector

Morad Aaboud, +2924 more
TL;DR: In this paper, measurements of top quark spin observables were performed in the dilepton final state, characterised by the presence of two isolated leptons (electrons or muons).
