Reducing systematic uncertainties in measurements of b→sll decays
ORAL
Abstract
In past years, measurements of rare b→sll decays have repeatedly indicated potential tensions with their Standard Model predictions. While current results are mostly limited by the size of the available data set, minimizing systematic uncertainties becomes increasingly important. A particular challenge is the modelling of hadronic effects due to the non-perturbative nature of QCD at the low energy scales in b-decays. This talk discusses long-established as well as novel model-independent analysis techniques for rare b-decay measurements and provides an outlook on systematic uncertainties at the potential FCC-ee.
