Abstract The ATLAS experiment at the Large Hadron Collider (LHC) employs a trigger system consisting of a first-level hardware trigger (L1) and a software-based high-level trigger. The L1 muon trigger system selects muon candidates, assigns them to the correct LHC bunch crossing …

A measurement of the parity-violating decay asymmetry parameter, ${\ensuremath{\alpha}}_{b}$, and the helicity amplitudes for the decay ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}({\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}){\mathrm{\ensuremath{\Lambda}}}^{0}(p{\ensuremath{\pi}}^{\ensuremath{-}})$ is reported. The analysis is based on 1400 ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}$ and ${\overline{\mathrm{\ensuremath{\Lambda}}}}_{b}^{0}$ baryons selected in $4.6\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton--proton collision data with a center-of-mass energy …

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 …
