Autoencoders for unsupervised anomaly detection in high energy physics
Journal of High Energy Physics, 2021 Autoencoders are widely used in machine learning applications, in particular for anomaly detection. Hence, they have been introduced in high energy physics as a promising tool for model-independent new physics searches.

Event-Based Anomaly Detection for Searches for New Physics
Universe, 2022 This paper discusses model-agnostic searches for new physics at the Large Hadron Collider using anomaly-detection techniques for the identification of event signatures that deviate from the Standard Model (SM).

Deep Set Auto Encoders for Anomaly Detection in Particle Physics
SciPost Physics, 2022 There is an increased interest in model agnostic search strategies for physics beyond the standard model at the Large Hadron Collider. We introduce a Deep Set Variational Autoencoder and present results on the Dark Machines Anomaly Score Challenge. We

Anomaly Detection for Resonant New Physics with Machine Learning
Physical Review Letters, 2018 Despite extensive theoretical motivation for physics beyond the Standard Model (BSM) of particle physics, searches at the Large Hadron Collider (LHC) have found no significant evidence for BSM physics.

Interpreting electroweak precision data including the W-mass CDF anomaly
Journal of High Energy Physics, 2022 We perform a global fit of electroweak data, finding that the anomaly in the W mass claimed by the CDF collaboration can be reproduced as a universal new-physics correction to the T parameter or |H † D μ H|2 operator.

Anomalies in Physical Cosmology
Annals of Physics, 2022 The ΛCDM cosmology passes demanding tests that establish it as a good approximation to reality. The theory is incomplete, of course, and open issues are being examined in research programs that promise to improve the cosmological tests and perhaps yield hints to a still better theory. But there is the possibility that less widely discussed observations,

Condensates and anomaly cascade in vector-like theories
Journal of High Energy Physics, 2021 We study the bilinear and higher-order fermion condensates in 4-dimensional SU(N) gauge theories with a single Dirac fermion in a general representation.

Physical Review Physics Education Research, 2022 Creating equitable learning environments has been an area of significant focus for physics education researchers in recent years. Here we introduce a framework that posits that grade penalty is a measure of academic self-concept and investigate if there ...

Anomalies of non-Abelian finite groups via cobordism
Journal of High Energy Physics, 2022 We use cobordism theory to analyse anomalies of finite non-abelian symmetries in 4 spacetime dimensions. By applying the method of ‘anomaly interplay’, which uses functoriality of cobordism and naturality of the η-invariant to relate anomalies in a group
