Measurements of ttbar and single top quark production at ATLAS

Mostrar otras versiones (1)

We present measurements made with the ATLAS detector of pair-produced top quarks and single top-quarks produced in sqrt(s)=7 TeV proton-proton collisions at the Large Hadron Collider. The cross-section of pair-produced top quarks is measured in several channels, including the single lepton, di-lepto...

description We present measurements made with the ATLAS detector of pair-produced top quarks and single top-quarks produced in sqrt(s)=7 TeV proton-proton collisions at the Large Hadron Collider. The cross-section of pair-produced top quarks is measured in several channels, including the single lepton, di-lepton and all-hadronic channel, with some channels using b-tagging information. The single top quark measurement is used to extract a lower limit on the CKM matrix element |Vtb|. A search for flavour-changing neutral-currents in single top production is also presented.
