A search is presented for production of a heavy up-type quark (t ) together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark.The search is based on 4.7 fb -1 of pp …

This Letter reports a search for a heavy particle that decays to WW using events produced in pp collisions at s=7TeV. The data were recorded in 2011 by the ATLAS detector and correspond to an integrated luminosity of 4.7 fb−1. WW→ℓνℓ′ν′ (ℓ,ℓ′=e …

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 …

A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy √=7 TeV is presented. The measurement covers the pseudorapidity ranges |η|<1.37| and 1.52≤|η|<2.37 in the transverse energy range 45≤ET<400 GeV. The …

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 …

A measurement of jet activity in the rapidity interval bounded by a dijet system is presented.Events are vetoed if a jet with transverse momentum greater than 20 GeV is found between the two boundary jets.The fraction of dijet events that survive the …

We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters.Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV.Events were selected using a minimum-bias trigger which required a charged …
