        Dark Matter: present and future of direct and indirect searches 50m
        Different techniques are being used to characterize the nature of Dark Matter, and to test whether its properties can explain the astronomers' puzzling observations: from underground detector to telescopes and satellites observing debris produced by Dark Matter annihilation in the Universe. I will give a review of direct and indirect searches, focusing on some of the latest results and future projects.

        Dark Matter in form of Weakly Interacting Massive Particles can annihilate and produce high energy (E>100MeV) gamma rays. Not deflected by magnetic field, they can be used to probe for the existence of DM in different location, e.g. at the Galactic centre or in dwarf spheroidal galaxies. Pair conversion space-based telescopes like Fermi-LAT, and an array of imaging atmospheric Cherenkov telescopes such as H.E.S.S. or the future CTA, have reached the sensitivity to study models with relic density thermally allowed. In this talk I will describe the functioning principles of these experiments and present some of the latest results.

        Monojets and Monophotons at ATLAS 45m
        Studies of events with single high energy jet or photon and large missing transverse momentum at the Large Hadron Collider is one of the most direct way to search for physics beyond the Standard Model. The backgrounds from Standard Model processes are dominated by jets/photons production associated with Z or W bosons that undergo leptonic decays to neutrinos and/or unidentified electrons or muons. The sensitivity to new physics signals relies on the good understanding and the accurate estimation of these backgrounds, and therefore the use of data-driven techniques is often required. In this talk I will present a compilation of the latest results from the monojets and monophotons searches based on the analysis of the 2011 and 2012 pp collision data collected with the ATLAS detector at a center-of-mass energy of 7 TeV and 8 TeV respectively. The results are interpreted in the context of various models Beyond the Standard Model but a particular attention is put on the standard "WIMP miracle" dark matter scenario, and the comparisons with the Direct and Indirect Detection experiments.

        Constraining mSUGRA with Dark Matter searches and the LHC 20m
        The LHC is steadily setting new limits on the supersymmetric, and particularly the mSUGRA parameter space. This talk will concern the intersection of astrophysical searches for dark matter and LHC searches, and the prospect of an ATLAS analysis of a plane of the parameter space.

        Search for SUSY in tau final states at ATLAS 20m
        Supersymmetry (SUSY) is a theoretically attractive model of particle physics which solves many of the theoretical problems of the Standard Model. An important one of these, dark matter, is solved in SUSY by the production of new stable, weakly interacting particles. With the unprecedented energy and luminosity of the Large Hadron Collider (LHC) large regions of the SUSY parameter space may be investigated and new heavy and rare particles can be searched for. A search for Supersymmetry with tau leptons in the final state, using data collected in 2011 at the ATLAS detector at the LHC will be presented. A combined search including final states with missing energy, jets, light leptons and at least one tau (one tau, two tau, tau+e and tau+mu) has been carried out. The results are used to set limits on the visible cross section of new physics processes and producing exclusion limits on a specific SUSY model (GMSB).

        Search for viable SUSY Models Discoverable at LHC 25m
        We present a framework for finding interesting regions of Supersymmetric parameter space, in light of experimental constraints and the possibility of detection at LHC using specific experimental signatures. The framework has been applied to find viable CMSSM models with $\tau$-lepton signatures observable with the 2012 LHC data.

        Making the most of Higgs to tautau 30m
        With a mass around 125 GeV, a handful of events are already expected to be present in the current ATLAS analysis searching for the SM higgs in the tau+tau-. Unfortunately, this channel has low mass resolution and high backgrounds, notably from Z decays, so it is difficult to establish a significant signal. In addition to reviewing the latest ATLAS results, this talk also presents some ideas that could be helpful in optimising the sensitivity to a signal, and eventually contribute to establishing the spin of a higgs candidate.

        If the neutralino is not dark matter, can it be heavier than the chargino? 25m
        If R-parity is violated, we no longer expect the neutralino to be dark matter. Then one might ask, is it possible for the chargino to be lighter than the neutralino in such scenarios? That would indeed lead to spectacular signals at the LHC, like chargino decays to three charged leptons. This possibility was studied using bayesian scanning in the form of SuperBAYES. Using Non-universal Higgs masses as well as gaugino mass parameters, in order to allow maximum freedom in the neutralino sector, the conclusion is that the chargino-neutralino mass difference is unlikely to go much below 130 MeV. However, with the most important competing decay channel for the chargino being to neutralino and pion, this is small enough to allow R-parity violating chargino decays at the LHC.
