Development of FastBDT Classifiers to Suppress Beam Background Clusters and Fake Photons / Priyanka Cheema ; Racha Cheaib ; Bruce Yabsley ; Chia-Ling Hsu ; et al [BELLE2-NOTE-PL-2023-003]
21 April 2023

We present an overview of the methodology used to develop FastBDT classifiers that suppress beam background clusters and fake photons, with the aim of using these classifiers to improve the signal-background separation power of the residual calorimeter energy E_ECL. [...]
