1. A new graph-neural-network flavor tagger for Belle~II and measurement of $\sin2\phi_1$ in $B^0 \to J/\psi K^0_\text{S}$ decays / Petros Stavroulakis [BELLE2-CONF-PROC-2024-009]
08 May 2024

We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral $B$ mesons produced in $\Upsilon(4S)$ decays. [...]

3. Optimisation of an upgrade to the Belle II experiment's inner tracker using simulated B0 -> Ks π+ π- γ decays / Petros Stavroulakis ; Christian Finck [BELLE2-MTHESIS-2022-008] Presented on 22 06 2022 MSc
2022
IPHC / Strasbourg
The Belle II experiment provides the ideal environment to study rare decay processes, since its collisions are free of contamination from physical background processes that can overshadow a potential discovery of new physics. [...]
