6 -Neutrino oscillations provide a natural setting in which to explore how quantum coherence evolves in realistic physical environments. The coherent evolution of neutrino states can persist over macroscopic distances, from terrestrial experiments to astrophysical baselines, making neutrinos an exceptional probe of decoherence and environmental effects.

8 -In the standard description, neutrinos are treated as isolated quantum systems whose flavour evolution is governed by the Schrödinger equation. In many realistic situations, however, particles propagate through complex environments that can induce decoherence and dissipation, requiring a more general framework based on the theory of open quantum systems.

10 -In this project, the student will learn the density-matrix formalism and apply it to neutrino oscillations. Starting from the standard two-flavour framework, the student will study how environmental effects modify flavour evolution and oscillation probabilities. Applications will be discussed in particle physics and astrophysical settings, such as neutrino propagation in matter and in dense or early-Universe environments.

12 -The project combines analytical calculations with simple numerical simulations and provides an introduction to modern techniques in quantum theory and their use in fundamental physics. Depending on progress and interest, the methods developed may also be applied to other oscillation phenomena, such as photon–dark-photon or photon–axion mixing, relevant to searches for physics beyond the Standard Model.
6 +With the acquisition of new data at a faster pace than ever, maintaining and verifying its quality is of paramount importance for greater precision measurements and improved searches for physics beyond the Standard Model at LHCb. In this project, the student will give the very first look at the newly-acquired 2026 data, i.e. only a few months old, through the study of the decay B→KS J/ψ. This high-statistics channel allows for a very clear study of, on the one hand, reconstruction effects, providing results of great impact for the whole collaboration, and on the other hand, detailed aspects of signal selection tools such as ML algorithms and particle identification, directly contributing to a world-leading search for New Physics. In both aspects, the student will have the opportunity to develop their knowledge of standard Particle Physics techniques, as well as develop their own tools and measurables for data and simulation quality evaluations.
