A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3  fb−1 of integrated luminosity at s√=8  TeV using data recorded with the ATLAS detector at the ...

This Letter presents a search for quantum black-hole production using 20.3  fb⎻¹ of data collected with the ATLAS detector in pp collisions at the LHC at √s=8  TeV. The quantum black holes are assumed to decay into a final ...

Measurements of four-lepton (4ℓ, ℓ=e,μ) production cross sections at the Z resonance in pp collisions at the LHC with the ATLAS detector are presented. For dilepton and four-lepton invariant mass regions mℓ+ℓ−>5  GeV and ...

A search for excited states of the B[± over c] meson is performed using 4.9  fb[superscript −1] of 7 TeV and 19.2  fb[superscript −1] of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is ...

The pT-differential production cross sections of the prompt charmed mesons $D^0, D^+, D^{*+}$ and $D_s^+$ and their charge conjugate in the rapidity interval -0.96 < $y_{cms}$ < 0.04 were measured in p-Pb collisions at a ...

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using 20.3  fb⎻¹ of s√=8  TeV pp collision data collected with the ATLAS detector at the Large Hadron ...

We present the first measurement at the LHC of exclusive J/ψ photoproduction off protons, in ultraperipheral proton-lead collisions at √sNN=5.02  TeV. Events are selected with a dimuon pair produced either in the rapidity ...

This Letter presents the first study of W±W±jj, same-electric-charge diboson production in association with two jets, using 20.3  fb−1 of proton-proton collision data at s√=8  TeV recorded by the ATLAS detector at the Large ...
