Search for single production of vector-like quarks decaying into a Wb final state at √s = 13 TeV with the ATLAS detector
(2024-08-28)
In this thesis, a search for single-production of vector-like quarks was performed using data collected during Run 2 of the Large Hadron Collider (LHC) by the ATLAS detector. The primary focus of this thesis was on the ......
Search for a light charged Higgs boson in t → H±b decays, with H± → cs, in pp collisions at √s = 13 TeV with the ATLAS detector
(2026-03-03)
A search for a light charged Higgs boson produced in decays of the top quark, t → H±b with H with H± → cs, is presented. This is a direct search for new physics beyond the Standard Model of ......
Towards a measurement of the tHq process in channels with hadronic tau lepton decays
(2023-10-05)
This thesis presents the first study to find events of the rare tHq process with ATLAS data in channels with hadronically decaying τ. A baseline framework is developed to select as many signal events as possible in ...
Evaluation of a Serial Powering Scheme and its Building Blocks for the ATLAS ITk Pixel Detector
(2022-11-02)
The high luminosity upgrade for the Large Hadron Collider (LHC) at CERN requires a complete redesign of the current inner detectors of ATLAS and CMS. These new inner detectors will consist of all-silicon tracking detectors, ...
Hybrid Pixel Readout Chip Verification, Characterization and Wafer Level Testing for the ATLAS-ITK Upgrade at the HL-LHC
(2023-07-04)
The HL-LHC upgrade starting in 2026 will provide an opportunity for new high-energy physics experiments, but also present challenges for its tracking detectors, particularly the pixel detectors close to the interaction ...
Development and Characterisation of Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2022-10-07)
With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity increases by a factor of five with respect to its design value from 2027. To keep the detectors at the ...
Towards High Precision Measurements of Higgs Boson Properties in the Di-Tau Decay with the ATLAS Detector
(2025-01-28)
The Standard Model of particle physics (SM) describes the known fundamental particles and their interactions. The model is found to be incomplete with a need for extensions in order to cover all current experimental ...
3D-Silicon and Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2020-10-30)
The future upgrade of the Large Hadron Collider to the High-Luminosity LHC demands new pixel detectors that can operate in environments with exceptionally high radiation. This requires investigations into new radiation-tolerant ...
Characterization and Quality Control of RD53A Readout Chips and Modules for the ATLAS ITk Pixel Detector
(2021-12-16)
In preparation of the upcoming high-luminosity upgrade of the Large Hadron Collider, the detectors of the major high-energy physics experiments at the accelerator facility will be upgraded as well. In case of the ATLAS ...
ATLAS ITk Silicon Strip Detector Performance Studies based on the System Test with Cosmic Muons at DESY
(2024-11-13)
The ATLAS experiment is the world’s largest collider-based particle physics experiment, located at the LHC in Geneva. An upgrade of the LHC will greatly increase the radiation environment and track density in the inner ...
