3. Search for B -> K(*)νν decays in the Belle II experiment / Güney Polat ; Isabelle Ripp-Baudot [BELLE2-MTHESIS-2021-064] Presented on 21 06 2019 MSc
2019
IPHC / Strasbourg
The B -> K(*)νν decay channel, never discovered to this day, is actively sought in the Belle II experiment: its branching ratio is in the order of magnitude of 10^(−6) and could be significantly changed if new physics occurred in the decay process. [...]
