Description

In the context of the Energy Frontier of Snowmass 2021, we are developing a neural network tagger for identifying the flavour of a jet with a physics focus on strange decays of Higgs bosons. The tagger will be deployed as part of prospect studies for SM H->ss measurements as well as for BSM heavy Higgs measurements, H(+)->cs, at future lepton colliders. In particular, these studies are performed using samples reconstructed using the International Large Detector at the proposed International Linear Collider. Jet-level variables as well the constituent particles within a jet are provided as inputs to the neural network, and different neural network architectures are studied. In this talk, we will present our progress to-date, including the performance of our preliminary jet taggers, and the work which remains to be done.
