147. Study of charmless B → η′K decays with the Belle II experiment / Valeria Fioroni ; Stefano Lacaprara [BELLE2-MTHESIS-2022-005] Presented on 13 12 2021 MSc
2021
Dipartimento di Fisica e Astronomia “Galileo Galilei” / Padova
The study of penguin-dominated B0 → η′K0S decays provides a good test of the Standard Model, since the CP violation measurement in this mode is sensitive to the presence of new physics effects in the loop. [...]

148. Development of a Semi-Inclusive Tagging Algorithm and Implementation of a Continuum Suppression in the Full Event Interpretation for the Belle II Experiment / Gianna Mönig [BELLE2-MTHESIS-2022-004] Presented on 31 08 2021 MSc
2021
Physikalisches Institut Bonn / Bonn
In this thesis a novel hybrid approach to tag-side reconstruction is presented, where the tag-side is only partially reconstructed in order to improve the purity compared to the inclusive tagging, while retaining a high efficiency. [...]

155. An electromagnetic calorimeter cluster classifier as a beam background suppressant in B^0 → D^{∗+} l^− ν_l decays at the Belle II experiment. / Kyle Amirie ; Steven Robertson [BELLE2-MTHESIS-2021-079] Presented on 01 11 2020 MSc
2020
McGill University / Montreal
The presence of beam background-related photons in the extra energy distributions of events reconstructed using Belle II data can make it difficult to accurately identify en- ergy missing from the detector that can be attributable to neutrinos or other hypothe- sized weakly interacting particles.
