Search for high-mass states with one lepton plus missing transverse momentum in $pp$ collisions at $\sqrt{s}$~=~8 TeV with the ATLAS detector
A search is presented for new high-mass states decaying to a lepton (electron or muon) plus missing transverse momentum using 20.3 fb$^{-1}$ of proton-proton collision data at $\sqrt{s}=8$ TeV recorded with the ATLAS experiment at the Large Hadron Collider. [...]

Search for microscopic black holes and string balls in final states with leptons and jets with the ATLAS detector at $\sqrt{s}=8$ TeV
A search for an excess of events with multiple high transverse momentum objects including charged leptons and jets is presented, using 20.3~fb$^{-1}$ of proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a centre-of-mass energy of $\sqrt{s} = 8$~TeV.

Search for the direct pair production of top squarks decaying to a b quark, a tau lepton, and weakly interacting particles, in $\sqrt{s} = 8 TeV$ pp collisions using $20 \; fb^{-1}$ of ATLAS data
Preliminary results of a search for direct pair production of supersymmetric partners of the top quark decaying via a $\tau$ slepton and with a gravitino in the final state ($ \tilde{t_1} \rightarrow b \nu_\tau \tilde{\tau_1} \rightarrow b \nu_\tau \tau \tilde G$) are reported. [...]

Constraints on New Phenomena via Higgs Coupling Measurements with the ATLAS Detector
The ATLAS experiment at the LHC has determined the couplings of the Higgs boson to other particles, as well as its mass, using the combination of measurements from multiple production and decay channels with up to 4.8 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=7$~TeV and 20.3 fb$^{-1}$ at $\sqrt{s}=8$~TeV.

Updated coupling measurements of the Higgs boson with the ATLAS detector using up to 25 fb$^{-1}$ of proton-proton collision data
This note presents an update of the measurements of the properties of the Higgs boson using the full run I collision data sample recorded by the ATLAS experiment at the LHC for the channels $H\to\gamma\gamma$, $H\to ZZ^*\to4\ell$, $H\to WW^*\to\ell\nu\ell\nu$, $H\to bb$, and$H\to \tau\tau$. [...]

First combination of Tevatron and LHC measurements of the top-quark mass
We present a combination of measurements of the mass of the top quark, $m_{\rm top}$, performed by the CDF and D0 experiments at the Tevatron collider and the ATLAS and CMS experiments at the Large Hadron Collider (LHC). [...]
