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.
