    “…We study the robustness of the LundNet taggers to non-perturbative and detector effects, and show how kinematic cuts in the Lund plane can mitigate overfitting of the neural network to model-dependent contributions. …”

    “…However, substructure predictions are sensitive to the details of the incalculable dark hadronization. We show that the Lund jet plane provides a very effective tool for designing observables that are resilient against the unknown impact of dark hadronization on the substructure properties of dark sector jets.…”

    “…The technique is based on reclustering the jet's constituents into several subjets, such that each subjet captures a single prong, and separately correcting the radiation pattern of each subjet using a data-driven correction in the Lund jet plane. It is shown that the correction procedure improves the agreement between data and simulation in multiple different substructure observables of two and three pronged jets. …”

    “…The assumption of linear confinement leads to a proportionality of the energy–momentum and space–time pictures of fragmentation for a simple [Formula: see text] system in the Lund string model. The hadronization of more complicated systems is more difficult to describe, and in the past only the energy–momentum picture has been implemented. …”
