Invertible networks or partons to detector and back again

M Bellagente, A Butter, G Kasieczka, T Plehn… - SciPost Physics, 2020 - scipost.org
For simulations where the forward and the inverse directions have a physics meaning,
invertible neural networks are especially useful. A conditional INN can invert a detector …

Jet Diffusion versus JetGPT--Modern Networks for the LHC

A Butter, N Huetsch, SP Schweitzer, T Plehn… - arXiv preprint arXiv …, 2023 - arxiv.org
We introduce two diffusion models and an autoregressive transformer for LHC physics

Measuring QCD splittings with invertible networks

S Bieringer, A Butter, T Heimel, S Höche, U Köthe… - SciPost Physics, 2021 - scipost.org
QCD splittings are among the most fundamental theory concepts at the LHC. We show how
they can be studied systematically with the help of invertible neural networks. These …

Generative Networks for LHC events

A Butter, T Plehn - Artificial intelligence for high energy physics, 2022 - World Scientific
LHC physics crucially relies on our ability to simulate events efficiently from first principles.
Modern machine learning, specifically generative networks, will help us tackle simulation …

Normalizing Flows for High-Dimensional Detector Simulations

F Ernst, L Favaro, C Krause, T Plehn, D Shih - arXiv preprint arXiv …, 2023 - arxiv.org
Whenever invertible generative networks are needed for LHC physics, normalizing flows

What's anomalous in LHC jets?

T Buss, BM Dillon, T Finke, M Krämer, A Morandini… - SciPost Physics, 2023 - scipost.org
Searches for anomalies are a significant motivation for the LHC and help define key analysis
steps, including triggers. We discuss specific examples how LHC anomalies can be defined …

How to GAN event unweighting

M Backes, A Butter, T Plehn, R Winterhalder - SciPost Physics, 2021 - scipost.org
Event generation with neural networks has seen significant progress recently. The big open
question is still how such new methods will accelerate LHC simulations to the level required …

Ephemeral learning-Augmenting triggers with online-trained normalizing flows

A Butter, S Diefenbacher, G Kasieczka, B Nachman… - SciPost Physics, 2022 - scipost.org
The large data rates at the LHC require an online trigger system to select relevant collisions.
Rather than compressing individual events, we propose to compress an entire data set at …
