6 -Rare decays involving tau leptons are currently one of the most exciting topics in particle physics, as they provide a unique opportunity to uncover hints of physics beyond the Standard Model. However, the reconstruction of tau leptons is one of the greatest experimental challenges in flavour physics, since their decays produce neutrinos that escape detection, severely degrading the resolution of key observables and increasing background contamination. In this project, the selected student will study both leptonic and hadronic tau decay modes, comparing their reconstruction performance using simulated LHCb data. Advanced analysis techniques, including Boosted Decision Trees, Neural Networks, and modern optimisation tools, will be used to maximise signal sensitivity and identify the most promising strategy for future measurements with tau leptons in the final state.
6 +We are building the first quantum simulator based on ultracold atoms in Galicia. The platform will use ultracold dysprosium gases to perform quantum simulation of strongly correlated matter. Achieving this goal requires precise control of magnetic fields for laser cooling, trapping, and manipulation of atomic interactions.
7 +This project focuses on the development of magnetic field setup and PID-based current stabilization electronics for this new experimental platform.

9 +The student will be involved in:
10 +
11 +* Designing and characterizing PID feedback systems for precise current and magnetic field control.
12 +* Constructing and testing magnetic field coils and associated electronics for laser cooling and trapping of dysprosium atoms.
13 +* Measuring magnetic field stability, homogeneity, and overall system performance.
14 +* Participating in scientific discussions within an international research team.

16 +This work will contribute directly to the construction of Galicia’s first cold-atom quantum simulator and provide hands-on experience in experimental quantum technologies, atomic physics, and advanced instrumentation.
