1. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities
Abstract : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. READ MORE

2. Linear response theory : from black hole thermalization to Weyl semimetals
Abstract : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. READ MORE

3. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC
Abstract : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. READ MORE

4. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics
Abstract : This thesis is concerned with experimental investigations of properties of the top quark and processes involving this particle. In the first part of the thesis, the first determination of the electric charge of the top quark is presented. READ MORE

5. Phenomenology of Inert Scalar and Supersymmetric Dark Matter
Abstract : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. READ MORE
