Heavy neutral leptons at a muon collider

Dataset contains data related to the study of the prospects for heavy neutral lepton (heavy neutrino) production in future experiments at muon collider described in the publication "Optimal search reach for heavy neutral leptons at a muon collider" published in Physics Letters B 841 (2023) 137945.This research was part of the project "Realistic simulations of exotic processes at future e+e- colliders" funded by National Science Centre, Poland, under grant agreement nr 2021/43/B/ST2/01778.MethodologyThe study was based on large event samples of different particle scattering processes, which can be observed at future Muon Collider, generated with the WHIZARD program. Considered signal process of heavy neutral lepton production was simulated according to the HeavyN model. Outputs from the WHIZARD program (lists of produced particles with their parameters) were then processed with the DELPHES framework to model Muon Collider detector performance. Event samples from detector simulation were stored in root format.Signal samples used for the analysis are too large (about 200 GB) to be stored. Included in the dataset are control scripts of the WHIZARD program which can be used to reproduce them. These are "pseudo-data" reflecting our current assumptions about how the future experiment at Muon Collider will perform and what model describes properly µ+µ- interactions. Also included are final numerical results on the expected coupling limits presented in the publication and the corresponding limits.Files:example WHIZARD scripts for generating signal samples for production of heavy neutring of 1 TeV mass, for Muon Collider running at 3 TeV and 10 TeV,archive with WHIZARD scripts for all considered heavy neutrino masses,CSV files with final analysis results: expected limits on the heavy neutrino coupling parameter V2lN as a function of its mass, for Muon Collider running at 3 TeV and 10 TeV,PDF and PNG files of the figure showing these limits (Fig. 3 from the paper).Software tools usedHeavyN model webpage: https://feynrules.irmp.ucl.ac.be/wiki/HeavyNWHIZARD Event Generator web page: https://whizard.hepforge.org/DELPHES: https://github.com/delphes/delphes
