1. A Search for Solar Neutralino Dark Matter with the AMANDA-II Neutrino Telescope
Abstract : A relic density of Weakly Interacting Massive Particles (WIMPs) remaining from the Big Bang constitutes a promising solution to the Dark Matter problem. It is possible for such WIMPs to be trapped by and accumulate in gravitational potentials of massive dense objects such as the Sun. READ MORE

2. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment
Abstract : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. READ MORE

3. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter
Abstract : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. READ MORE

4. A Search for Dark Matter in the Sun with AMANDA and IceCube
Abstract : A search for weakly interacting massive particles (WIMPs) annihilating in the Sun was performed with the IceCube and AMANDA neutrino telescopes, using data from 2008 corresponding to 149 days of livetime. Assuming that particles in the dark matter halo scatter and accumulate in the centre of the Sun, Majorana WIMPs may pair-wise annihilate and give rise to a neutrino signal detectable in an experiment at Earth.

5. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube
Abstract : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. READ MORE
