Graph Neural Networks for Particle Reconstruction in High Energy Physics detectors
Xiangyang Ju,Steven Farrell,Paolo Calafiura,Daniel Murnane,Prabhat,Lindsey Gray,Thomas Klijnsma,Kevin Pedro,Giuseppe Benedetto Cerati,Jim Kowalkowski,Gabriel Perdue,Panagiotis Spentzouris,Nhan Tran,Jean-Roch Vlimant,Alexander Zlokapa,Joosep Pata,Maria Spiropulu,Sitong An,Adam Aurisano,J. Hewes,A. Tsaris,Kazuhiro Terao,T. Usher +22 more
TL;DR: This work demonstrates the applicability of GNNs to these two diverse particle reconstruction problems, which have unique challenges and characteristics, but both have high dimensionality, high degree of sparsity, and complex geometric layouts.

ColliderBit: a GAMBIT module for the calculation of high-energy collider observables and likelihoods
Csaba Balázs,Csaba Balázs,Andy Buckley,Lars A. Dal,Ben Farmer,Paul Jackson,Paul Jackson,Abram Krislock,Anders Kvellestad,Daniel Murnane,Daniel Murnane,Antje Putze,Are Raklev,Christopher Sean Rogan,A. F. Saavedra,A. F. Saavedra,Pat Scott,Christoph Weniger,Martin White,Martin White +19 more
TL;DR: CollaboratorBit as mentioned in this paper is a new code for the calculation of high energy collider observables in theories of physics beyond the Standard Model (BSM) ColliderBit features a generic interface to BSM models, a unique parallelised Monte Carlo event generation scheme suitable for large-scale supercomputer applications, and a number of LHC analyses, covering a reasonable range of the BSM signatures currently sought by ATLAS and CMS.

Track Seeding and Labelling with Embedded-space Graph Neural Networks.
Nicholas Choma,Daniel Murnane,Xiangyang Ju,Paolo Calafiura,Sean Conlon,Steven Farrell,Prabhat,Giuseppe Benedetto Cerati,Lindsey Gray,Thomas Klijnsma,Jim Kowalkowski,Panagiotis Spentzouris,Jean-Roch Vlimant,Maria Spiropulu,Adam Aurisano,J. Hewes,A. Tsaris,Kazuhiro Terao,T. Usher +18 more
TL;DR: A suite of extensions to the original model of graph neural networks, with encouraging results for hitgraph classification are presented, and increased performance is explored by constructing graphs from learned representations which contain non-linear metric structure, allowing for efficient clustering and neighborhood queries of data points.
