Improved selective background Monte Carlo simulation at Belle II with graph attention networks and weighted events

no code implementations12 Jul 2023 Boyang Yu, Nikolai Hartmann, Luca Schinnerl, Thomas Kuhr

When measuring rare processes at Belle II, a huge luminosity is required, which means a large number of simulations are necessary to determine signal efficiencies and background contributions.

Graph Attention

Ultra-High-Resolution Detector Simulation with Intra-Event Aware GAN and Self-Supervised Relational Reasoning

1 code implementation7 Mar 2023 Hosein Hashemi, Nikolai Hartmann, Sahand Sharifzadeh, James Kahn, Thomas Kuhr

Simulating high-resolution detector responses is a storage-costly and computationally intensive process that has long been challenging in particle physics.

Shared Data and Algorithms for Deep Learning in Fundamental Physics

1 code implementation1 Jul 2021 Lisa Benato, Erik Buhmann, Martin Erdmann, Peter Fackeldey, Jonas Glombitza, Nikolai Hartmann, Gregor Kasieczka, William Korcari, Thomas Kuhr, Jan Steinheimer, Horst Stöcker, Tilman Plehn, Kai Zhou

We introduce a Python package that provides simply and unified access to a collection of datasets from fundamental physics research - including particle physics, astroparticle physics, and hadron- and nuclear physics - for supervised machine learning studies.
