Data-driven Continuum Monte Carlo Corrections for Belle and Belle II — •Lena Feld1, Florian Bernlochner2, Pablo Goldenzweig1, and Markus Prim1 for the Belle II collaboration — 1Karlsruher Institut für Technologie — 2Rheinische Friedrich-Wilhelms-Universität Bonn

The Belle and Belle II experiments record BB decays at the Y(4S) resonance. For background determination, continuum data without B meson decays is recorded 60 MeV below the resonance. We present a method to improve the simulation of the continuum in a data-driven way. For this purpose, a multivariate classifier is trained to distinguish the Monte Carlo prediction from the continuum data. The classification is used to reweight the individual events of the Monte Carlo prediction. We present early studies on the improvability of the continuum Monte Carlo sample.
