INSTANTONS AND CHIRAL ANOMALY IN FUZZY PHYSICS [PDF]
International Journal of Modern Physics A, 2001 In continuum physics, there are important topological aspects like instantons, θ-terms and the axial anomaly. Conventional lattice discretizations often have difficulties in treating one or the other of these aspects. In this paper, we develop discrete quantum field theories on fuzzy manifolds using noncommutative geometry.

Long-Lived Particles Anomaly Detection with Parametrized Quantum Circuits
Particles, 2023 We investigate the possibility to apply quantum machine learning techniques for data analysis, with particular regard to an interesting use-case in high-energy physics.

Testing Lorentz invariance violations in the tritium beta-decay anomaly [PDF]
, 2000 We consider a Lorentz non-invariant dispersion relation for the neutrino, which would produce unexpected effects with neutrinos of few eV, exactly where the tritium beta-decay anomaly is found.

Challenges for unsupervised anomaly detection in particle physics
Journal of High Energy Physics, 2022 Anomaly detection relies on designing a score to determine whether a particular event is uncharacteristic of a given background distribution. One way to define a score is to use autoencoders, which rely on the ability to reconstruct certain types of data

SciPost Physics, 2022 We propose a new method to define anomaly scores and apply this to particle physics collider events. Anomalies can be either rare, meaning that these events are a minority in the normal dataset, or different, meaning they have values that are not ...

New Physics Agnostic Selections For New Physics Searches [PDF]
EPJ Web of Conferences, 2020 We discuss a model-independent strategy for boosting new physics searches with the help of an unsupervised anomaly detection algorithm. Prior to a search, each input event is preprocessed by the algorithm - a variational autoencoder (VAE).

Muon g-2: Review of Theory and Experiment [PDF]
, 2007 A review of the experimental and theoretical determinations of the anomalous magnetic moment of the muon is given. The anomaly is defined by a=(g-2)/2, where the Land\'e g-factor is the proportionality constant that relates the spin to the magnetic ...

Comment on anomaly matching in N=1 supersymmetric QCD [PDF]
, 1998 An attempt is made at a systematic approach to anomaly matching problem in non-Abelian electric-magnetic duality in N=1 supersymmetric QCD. A strategy we employ is somewhat analogous to anomaly analyses in grand unified models where the anomaly ...
