Extending the Full Event Interpretation to the Y(5S) system at Belle — •Moritz Bauer and Pablo Goldenzweig — Karlsruhe Institute of Technology, Karlsruhe, Germany

The Belle experiment has, in addition to the data collected at the Υ(4S) resonance, also collected 121 fb−1 of data at the Υ(5S) resonance. The decay products of this resonance include Bs mesons which present interesting channels to test the standard model. Until now, it has not been possible to apply Belle II’s new B meson tagging algorithm, the Full Event Interpretation (FEI), to the Υ(5S) dataset. This exclusive tagging algorithm uses O(10k) decay channels to recombine final-state particles to B mesons.

This talk presents the development and validation of the FEI at the Υ(5S) resonance.
