Masked Particle Modeling on Sets: Towards Self-Supervised High Energy Physics Foundation Models

1 code implementation24 Jan 2024 Lukas Heinrich, Tobias Golling, Michael Kagan, Samuel Klein, Matthew Leigh, Margarita Osadchy, John Andrew Raine

We propose masked particle modeling (MPM) as a self-supervised method for learning generic, transferable, and reusable representations on unordered sets of inputs for use in high energy physics (HEP) scientific data.

Improving new physics searches with diffusion models for event observables and jet constituents

no code implementations15 Dec 2023 Debajyoti Sengupta, Matthew Leigh, John Andrew Raine, Samuel Klein, Tobias Golling

We introduce a new technique called Drapes to enhance the sensitivity in searches for new physics at the LHC.

EPiC-ly Fast Particle Cloud Generation with Flow-Matching and Diffusion

no code implementations29 Sep 2023 Erik Buhmann, Cedric Ewen, Darius A. Faroughy, Tobias Golling, Gregor Kasieczka, Matthew Leigh, Guillaume Quétant, John Andrew Raine, Debajyoti Sengupta, David Shih

In addition, we introduce \epcfm, the first permutation equivariant continuous normalizing flow (CNF) for particle cloud generation.

PC-Droid: Faster diffusion and improved quality for particle cloud generation

no code implementations13 Jul 2023 Matthew Leigh, Debajyoti Sengupta, John Andrew Raine, Guillaume Quétant, Tobias Golling

Building on the success of PC-JeDi we introduce PC-Droid, a substantially improved diffusion model for the generation of jet particle clouds.

$ν^2$-Flows: Fast and improved neutrino reconstruction in multi-neutrino final states with conditional normalizing flows

1 code implementation5 Jul 2023 John Andrew Raine, Matthew Leigh, Knut Zoch, Tobias Golling

In this work we introduce $\nu^2$-Flows, an extension of the $\nu$-Flows method to final states containing multiple neutrinos.
