Research Phase Master
General Information
The research phase of the Master studies in Physics consists of two parts: the scientific research project and the Master thesis proper. The topics of these parts are closely connected and build apon each other.
Below you find the thesis topics offered by the IKTP. If you are interested in one of the topics, please, contact the relevant group leader.

Topics
In parallel to our analysis of WZ final states at high transverse momentum we want to search for deviations from the Standard Model from new heavy particles decaying into a WZ boson pair.
The simulation program Sherpa can currently only simulate decay cascades with up to 3 final state particles in each step. For decays of the Higgs boson into 4 fermions via WW or ZZ diagrams it becomes important to simulate the full 1->4 decay. This thesis is about implementing such decays and make phenomenological comparisons to existing calculations.

Themenübersicht:
Bachelor Thesis, Research Studies Master, Master Thesis in Experimental Particle Physics
- Multivariate analysis, machine learning and artificial intelligence
- Optimisation of data analyses for particle searches and reconstruction of particle decays
- Application and development of software for statistical data analysis
One of the research activities of the ATLAS group at the Institute of Nuclear and Particle Physics is the search for new Higgs bosons in extensions of the Standard Model at the Large Hadron Collider (LHC). A large data set is available from ATLAS Run-2 and Run-3 with a total luminosity of 200 fb-1, which can be analysed. More data are currently being recorded by ATLAS.
In many scenarios beyond the Standard Model, the decay of the new Higgs bosons is into a pair of tau leptons. We therefore study the hadronic decay of such tau leptons in detail, in particular, to obtain a high significance for the Higgs signal, and a large suppression of backgrounds.
In the data analyses, we exploit advanced statistical methods and very often apply methods of machine learning to optimize the selection algorithms or parameter settings.
The topics of the Bachelor and Master theses will be defined individually according to your interest and to the current state of research.
In the thesis project, you will learn software-based methods of data analysis and statistics, the application of machine learning tools, and the use of modern particle detectors.
You should bring a basic knowledge of particle physics. Programming skills would be an asset, but we will also provide introductory sessions to all necessary programming and analysis tools.

Bachelor Thesis, Research Studies Master, Master Thesis in Experimental Particle Physics
- Machine learning und artificial neural networks
- Optimisation of the energy measurement of photons, electrons and hadronic jets with Liquid-Argon calorimeters
- Programming or simulation of electronic and digital signal processing
- Statistical analysis of measurement data
The Liquid-Argon Calorimeters (LAr Calorimeters) of the ATLAS detector at the LHC are going to be upgraded with new readout electronics for operating at highest LHC luminosities. The calorimeter signals shall be reconstructed with improved energy and spatial resolution so that particles produced in proton-proton collisions can be identified with higher precision. The goal is, for example, an improved detection of Higgs boson decays with the ATLAS detector.
The particle identification and energy reconstruction must be performed in real-time, and the time to provide the energy calculation in each detector cell must not take longer than 0.5 μs. For this reason, we use modern and fast programmable electronic circuits, so-called Field Programmable Gate Arrays (FPGAs) for signal reconstruction. We exploit deep learning methods and artificial intelligence to optimize our measurements.
In the Bachelor or Master thesis, the energy reconstruction of the ATLAS LAr Calorimeters shall be improved using machine learning approaches.
In the research project, you will learn the application of machine learning tools (e.g. keras), software-based data analysis, and the functioning of a modern particle detector and electronic readout systems.
If you are interested you may also learn about programming of FPGAs using the programming language VHDL. You can get involved in the optimisation and application of machine learning algorithms running on FPGA devices.
You should bring a basic knowledge of particle physics, and the motivation to learn more about machine learning and/or FPGA programming. Basic programming skills are an asset. We also provide introductory sessions to VHDL and the analysis tools needed for your work.
