The contract began on 6 February 2023, during the final thesis-writing phase of the PhD. The doctoral degree was awarded on 4 December 2023.
Physics measurements
- Charm-strange baryon (Ξ+c) production in pp and Pb–Pb collisions in LHC Run 3 (2022–26), using machine learning techniques.
- Machine learning-based signal selection. Extracted the invariant-mass signals of Ξ+c → pK−π+ and Λ+c → pK−π+ with Boosted Decision Trees (BDTs) to optimize signal-to-background separation, particularly in the low-transverse-momentum region, in pp collisions.
- Physics analysis and dissemination. Measured the charm baryon-to-baryon ratio Ξ+c/Λ+c in pp collisions at √s = 13.6 TeV, compared the results with theoretical QCD models, and presented these findings for the first time in two talks (Talk 1, Talk 2) at the SQM 2026 conference.
Software development
- Software tools for data-driven calibration of Monte Carlo simulations.
- Main developer of the software implementation of a method that modifies the spatial and momentum resolutions of reconstructed tracks in the simulation to reproduce those estimated in data with data-driven techniques. The approach has since been adopted in multiple ALICE heavy-flavor analyses to help reduce systematic uncertainties. This is crucial for the measurements of all hadrons decaying far from the primary vertex, especially hadrons containing charm or beauty quarks.

Thesis: “Prompt and non-prompt J/ψ production in Pb–Pb collisions at √sNN = 5.02 TeV with ALICE experiment”
Physics measurements
- Prompt and non-prompt J/ψ production in Pb–Pb collisions at √sNN = 5.02 TeV in the ALICE experiment.
- Extraction of non-prompt J/ψ fractions using two-dimensional simultaneous likelihood fits on the invariant mass and decay length of J/ψ candidates, reconstructed via the J/ψ → e+e− decay channel at midrapidity using datasets collected during LHC Run 2.
- Determination of nuclear modification factors and production yields of prompt and non-prompt J/ψ as a function of transverse momentum and collision centrality.
Detector development
- Contribution to the development of the ALICE Fast Interaction Trigger (FIT) detector for LHC Run 3 during Long Shutdown 2 (LS2).
