Search for direct pair production of a chargino and a neutralino decaying to the 125 GeV Higgs boson with 20.3 fb$^{-1}$ of 8 TeV pp collisions using the ATLAS detector
/ Gignac, Matthew (Department of Physics, University of British Columbia)
A search is presented for the direct pair production of a chargino and a neutralino $pp$ $\rightarrow$ $\tilde{\chi}^{\pm}_{1}$$\tilde{\chi}^{0}_{2}$, where the chargino decays to the lightest neutralino and the $W$ boson, $\tilde{\chi}^{\pm}_{1}$ $\rightarrow$ $\tilde{\chi}^{0}_{1}$ $(W^{\pm}\to\ell^{\pm}\nu)$, while the neutralino decays to the lightest neutralino and the 125~GeV Higgs boson, $\tilde{\chi}^{0}_{2}$ $\rightarrow$ $\tilde{\chi}^{0}_{1}$ $(h\to bb/\gamma\gamma/\ell^{\pm}\nu qq)$. The final states considered for the search have large missing transverse momentum, an isolated electron or muon, and one of the following: either two jets identified as originating from bottom quarks, or two photons, or a second electron or muon with the same electric charge.

8 TeV Non-Resonant Dilepton Search at ATLAS
/ Savage, Graham (Department of Physics, Royal Holloway and Bedford New College)
A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The full LHC 2012 proton-proton collision dataset recorded by the ATLAS detector is used, corresponding to 20 fb-1 at √s = 8 TeV. [...]

Physics prospects with the upgraded ATLAS detector
/ Volpi, Guido (INFN Pisa and Universita' di Pisa, Dipartimento di Fisica)
Run-I at the LHC has been very successful, including the discovery of a new particle with a mass of about 125 GeV and with properties compatible with those of the Standard Model Higgs boson within uncertainties. Precise measurements of the properties of this boson, and the discovery of new physics beyond the Standard Model, are primary goals of future running at the LHC. [...]
