FCC feasibility studies: Impact of tracker- and calorimeter-detector performance on jet flavor identification and Higgs physics analyses Open
The ambitious physics program planned for the Future Circular Collider electron-positron phase imposes stringent constraints on detector performance. This study systematically investigates how different detector configurations impact jet f…

Searching for Pairs of Higgs Bosons in the LHC Run 2 Dataset Open
The discovery of the Higgs boson confirms the existence of a scalar sector of the standard model, responsible for electroweak symmetry breaking, but the nature and properties of the potential at the origin of this mechanism are still unkno…

Cooling and Timing Tests of the ATLAS Fast TracKer VME Boards Open
The Fast TracKer (FTK) is an ATLAS trigger upgrade built for full-event, low-latency, high-rate tracking. The FTK core, made of 9U VME boards, performs the most demanding computational task. The associative memory board (AMB) serial link p…

Higgs Boson Pair Production at Colliders: Status and Perspectives Open
This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson self-coupling, with the wish to serve as a useful guide for t…

The ATLAS Fast Tracker Processing Units - input and output data preparation Open
The ATLAS Fast TracKer(FTK) is a custom hardware system for fast, associative memory based track reconstruction. It will provide tracking information within the full acceptance of the inner tracking detectors to the high level trigger at a…

Search for the Flavor-Changing Neutral Current in Top Pair Events in sqrt(s) = 8 TeV Proton-Proton Collisions at the Large Hadron Collider Using the ATLAS Detector Open
In this dissertation, a search for the flavor-changing neutral current in top-antitop events is presented. The flavor-changing neutral current is forbidden at tree level in the Standard Model and suppressed at higher order due to the GIM m…
