Reconstruction of B mesons using machine learning methods — Florian Bernlochner2, •Tobias Böckh1, Jochen Gemmler1, Pablo Goldenzweig1, and James Kahn1 for the Belle II collaboration — 1Karlsruher Institut für Technologie — 2Rheinische Friedrich-Wilhelms-Universität Bonn
The Belle II experiment records events of two B mesons decaying, via intermediate resonances, into final state particles. This work presents a deep learning approach to reconstruct a B meson. For this purpose, a network is trained to predict for each final state particle from which B meson it originated. Subsequently, particles from a common mother are combined to predict properties of the B meson.
