Juhee Song (IIHE) wins the best poster prize at the 16th International Workshop on Top Quark Physics, TOP2023. The annual workshop was held from Sept 24 to 29 in Michigan, USA. The workshop brings together experimentalists and theorists to discuss the latest developments in the field. Juhee presented a poster on DNN-based identification of additional b jets for a differential ttbb cross section measurement, a measurement she performed on the Run-2 LHC data collected by the CMS experiment. In differential measurements of the ttbb process, observables related to the b jets not originating from top quark decays are of special interest to probe the multi-scale QCD nature of the ttbb process, and the description of the additional b jet radiation via different simulation tools. In order to access these additional b jets, identification algorithms have to be applied to determine which of the b jets recorded in the detector are the b jets of interest. This was achieved via a DNN-based method. Juhee is working on a PhD thesis on the measurements of heavy-flavour jets produced in association with top quarks.
