Search for same-sign top-quark production and fourth-generation down-type quarks in pp collisions at $ \sqrt {s} = {7}\;{\text{TeV}} $ with the ATLAS detector

G. Aad, B. Abbott, J. Abdallah, S. Abdel Khalek et autres

Abstract A search is presented for same-sign top-quark production and down-type heavy quarks of charge −1/3 in events with two isolated leptons (e or μ) that have the same electric charge, at least two jets and large missing transverse momentum. The data …

Properties of jets measured from tracks in proton-proton collisions at center-of-mass energy s=7 TeV with the ATLAS detector

G. Aad, B. Abbott, J. Abdallah, A. A. Abdelalim et autres

Jets are identified and their properties studied in center-of-mass energy $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ proton-proton collisions at the Large Hadron Collider using charged particles measured by the ATLAS inner detector. Events are selected using a minimum bias trigger, allowing jets at very low …
