Search for Pair Production of a New Heavy Quark that Decays into a W Boson and a Light Quark in pp Collisions at √s̅ =8 TeV with the ATLAS Detector
(American Physical Society, 2015-12-22)
A search is presented for pair production of a new heavy quark (Q) that decays into a W boson and a light quark (q) in the final state where one W boson decays leptonically (to an electron or muon plus a neutrino) and the ...
Measurement of Colour Flow with the Jet Pull Angle in tt̅ Events Using the ATLAS Detector a √s̅ = 8 TeV
(Elsevier Science B.V., 2015-09-26)
The distribution and orientation of energy inside jets is predicted to be an experimental handle on colour connections between the hard-scatter quarks and gluons initiating the jets. This Letter presents a measurement of ...
Analysis of Events with B-Jets and a Pair of Leptons of the Same Charge in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
An analysis is presented of events containing jets including at least one b tagged jet, sizeable missing transverse momentum, and at least two leptons including a pair of the same electric charge, with the scalar sum of ...
Search for Vectorlike B Quarks in Events with One Isolated Lepton, Missing Transverse Momentum, and Jets at √s̅ = 8 TeV with the ATLAS Detector
(Amer Physical Soc, 2015-06-19)
A search has been performed for pair production of heavy vectorlike down-type (B) quarks. The analysis explores the lepton-plus-jets final state, characterized by events with one isolated charged lepton (electron or muon), ...
A Search for High-Mass Resonances Decaying to τ⁺τ⁻ in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
A search for high-mass resonances decaying into τ⁺τ⁻ final states using proton-proton collisions at √s̅ = 8 TeV produced by the Large Hadron Collider is presented. The data were recorded with the ATLAS detector and ...
Measurement of the Charge Asymmetry in Highly Boosted Top-Quark Pair Production in √s̅ = 8 TeV pp Collision Data Collected by the ATLAS Experiment
(Elsevier Science BV, 2016-03-02)
In the pp → tt̅ process the angular distributions of top and anti-top quarks are expected to present a subtle difference, which could be enhanced by processes not included in the Standard Model. This Letter presents a ...
