Working group Sascha Caron

I'm a particle physicists and work since begin 2006 for the ATLAS experiment at CERN (Geneva). I was a member of the DØ experiment at Fermilab (Chicago) between 2004 and 2006 and a member of the H1 experiment at DESY (in Hamburg) between 1998 and 2004.

Together with my group I try to discover signals from new physics, e.g. physics outside our current theory of the microscopic world (the so-called Standard Model). For this we develop data science methods for astroparticle physics problems, astrophysics and theory.

ATLAS Experiment


ATLAS Experiment
This is a collection of work that we are doing in ATLAS (including some links to notes, papers and relevant webpages):

Some coordination activities of group members: Monte Carlo studies, Data analysis, software, trigger, upgrade activities:

- Interested in really old stuff? My Ph.D. thesis and diploma thesis at the RWTH Aachen can be found here.
Data Science and Machine Learning for Particle Physics & Dark Matter


Examples of our data science related research topics outside ATLAS are (see also phenomenology papers)::
- The autosourceid project to automatize point source detection and classification, see AutoSourceID
(use cases for gamma ray and optical data)
- Darkmachines initiative on Optimisation algorithms for high-dimensional particle and astrophysics applications, e.g. : first paper
- The darkmachines unsupervised challenge, see: benchmark dataset and LHC challenge
- Developing various anomaly score algorithms for LHC data analysis, e.g. rare+different
- A database for high-parameteric data in the fields of Astro and Particlephysic : Prototype at idarksurvey (based on SPOT developed with the Dutch escience center)
- Using Machine Learning and advanced data analysis to identify the nature of Dark Matter. We initated the worldwide first workshop and build a community. Go to darkmachines.org
- The the idark project with the Dutch escience center
- The BSM-AI project to use machine learning to learn the global model-data: susy-ai & bsm-ai
- The ASTRO-AI projec to use ConvNets for Astrophysics, a first paper is : ConvNets for gamma-rays
- The DeepXS project to learn cross sections: DeepXS
- Exploring physical models with active learning
- Building deep generative model based Event Generators
- Data-derived searches for New Physics and search algorithms:
work in H1 experiment, , work in ATLAS



We published a few papers outside of the ATLAS, D0 and H1 collaborations. Full list of papers containing my name can be found here here . Other examples are (not complete):
Our group members also collaborate on research topics with Astronomers and Astrophysics, especially with the application of Machine Learning methods. Examples are papers on Astroseismology and the Event Horizon Projects by Luc Hendriks and various projects within the darkmachines initiative.

Brief CV

Sascha Caron is associate professor at the Radboud University in Nijmegen and a senior researcher within the Nikhef consortium. He is a leading researcher at the ATLAS experiment at CERN where he was co-responsible for the first searches for Dark Matter and Supersymmetry and initiated generic “data-derived” searches for new physics. Caron also works on phenomenology, astrophysics and the application of machine learning methods. His research focus is the search for signals from new physics. Caron is a main author of >70 publications with >6000 citations and co-author of >900 publications (h-index>100).
Other recent activities: He is the PI of the ’IDARK’ project with the Netherlands eScience Center, the ’quantum generators’ project with the Dutch supercomputer center SURFsara and the AI/ML convener of the “Les Houches workshop\ ” series for Physics at TeV colliders. He also co-founded and co-coordinates the international darkmachines initiative, which aims to accelerate searches for Dark Matter with machine learning.
