The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process View the MathML source, where ℓ=e,μ. The data sample corresponds ...

A measurement of the cross section for the production of top quark-antiquark pairs (t (t) over bar) in association with a vector boson V (W or Z) in proton-proton collisions at root s = 8 TeV is presented. The results are ...

A search is presented for standard model (SM) production of four top quarks (tt¯tt¯)(tt¯tt¯) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb−1 recorded at a ...

Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
