1. Inclusive B-Meson Tagging for an R(D*) Measurement at Belle II / Sofia Palacios Schweitzer ; Thomas Kuhr ; Thomas Lueck [BELLE2-MTHESIS-2023-032] Presented on 13 09 2022 MSc
LMU / Munich
The world average of previous R(D(*)) measurements, defined as R(D(*)) = BR(B -> D(*) tau nu) / BR(B -> D(*) l nu) with l = e, mu, shows a 3.3 sigma deviation from Standard Model predictions, which could indicate some New Physics phenomenon, such as the existence of Leptoquarks. [...]

4. Improved Selective Background Monte Carlo Simulation at Belle II with Graph Attention Networks and Weighted Events / Boyang Yu ; Thomas Kuhr ; Nikolai Hartmann [BELLE2-MTHESIS-2022-017] Presented on 14 09 2021 MSc
LMU Munich / Munich, Germany
When measuring rare processes such as B → K(∗)νν¯ or B → lνγ, a huge luminosity is required, which means a large number of simulations are necessary to determine signal efficiencies and background contributions. [...]
