Results are reported from a search for new physics processes in events containing a single isolated high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse mom...
An inclusive search is presented for new heavy particle pairs produced in s=7 TeV proton-proton collisions at the LHC using 4.7±0.1 fb-1 of integrated luminosity. The selected events are analyzed in...
We present a search for a light (mass <2GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted ''lepton-jets''....
This Letter presents the results of a search for a heavy particle decaying into an e±μ∓ , e±τ∓ , or μ±τ∓ final state in pp collisions at s=7 TeV . The data were recorded with the ATLAS detector at the...
In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H (+), t → bH (+), in addition to the Standard Model decay t → bW. Since W boso...
Results are presented from a search for long-lived neutralinos decaying into a photon and an invisible particle, a signature associated with gauge-mediated supersymmetry breaking in supersymmetric mod...
A search for new physics is performed using events with isolated same-sign leptons and at least two bottom-quark jets in the final state. Results are based on a sample of proton-proton collisions coll...
A search is presented for direct top squark pair production in final states with one isolated electron or muon, jets, and missing transverse momentum in proton-proton collisions at a center-of-mass en...
The results of a search for direct pair production of supersymmetric partners of the top quark in 13.0 \ifb\ of integrated luminosity from LHC collisions at 8~\TeV\ collected by the ATLAS detecto...
A search for direct pair production of bottom squarks, each decaying into a bottom quark and a neutralino, is performed in events with large missing transverse momentum and 2 bjets in the final state ...
