Persistent homology of collider observations: When (w)hole matters

Physics Letters B, 2023
Topological invariants have played a fundamental role in the advancement of theoretical high energy physics. Physicists have used several kinematic techniques to distinguish new physics predictions from the Standard Model (SM) of particle physics at ...

Energy flow networks: deep sets for particle jets

Journal of High Energy Physics, 2019
A key question for machine learning approaches in particle physics is how to best represent and learn from collider events. As an event is intrinsically a variable-length unordered set of particles, we build upon recent machine learning efforts to learn ...

Soft Photoproduction Physics [PDF]

, 1995
Several topics of interest in soft photoproduction physics are discussed. These include jet universality issues (particle flavour composition), the subdivision into event classes, the buildup of the total photoproduction cross section and the effects of ...

Event-by-event fluctuations and the QGP [PDF]

, 2001
We discuss the physics underlying event-by-event fluctuations in relativistic heavy ion collisions. We will emphasize how the fluctuations of particle ratios can be utilized to explore the properties of the matter created in these collisions.

GANplifying event samples

SciPost Physics, 2021
A critical question concerning generative networks applied to event generation in particle physics is if the generated events add statistical precision beyond the training sample.

QCD and Monte Carlo event generators [PDF]

, 2006
Shower Monte Carlo event generators have played an important role in particle physics. Modern experiments would hardly be possible without them. In this talk I discuss how QCD physics is incorporated into the mathematical structure of these programs and ...

Exploring End-to-end Deep Learning Applications for Event Classification at CMS [PDF]

EPJ Web of Conferences, 2019
An essential part of new physics searches at the Large Hadron Collider (LHC) at CERN involves event classification, or distinguishing potential signal events from those coming from background processes. Current machine learning techniques accomplish this

Trans-Planckian physics and signature change events in Bose gas hydrodynamics [PDF]

, 2007
We present an example of emergent spacetime as the hydrodynamic limit of a more fundamental microscopic theory. The low-energy, long-wavelength limit in our model is dominated by collective variables that generate an effective Lorentzian metric.
