Higgs physics confronts the MW anomaly

open access: yesPhysics Letters B, 2022
The recent high-precision measurement of the W mass by the CDF collaboration is in sharp tension with the Standard Model prediction as obtained by the electroweak fit. If confirmed, this finding can only be explained in terms of new physics effects.

A Qualitative Strategy for Fusion of Physics into Empirical Models for Process Anomaly Detection

open access: yesEnergies, 2022
To facilitate the automated online monitoring of power plants, a systematic and qualitative strategy for anomaly detection is presented. This strategy is essential to provide credible reasoning on why and when an empirical versus hybrid (i.e., physics ...

Finding new physics without learning about it: anomaly detection as a tool for searches at colliders

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper we propose a new strategy, based on anomaly detection methods, to search for new physics phenomena at colliders independently of the details of such new events.

Autoencoders for unsupervised anomaly detection in high energy physics

open access: yesJournal 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

open access: yesUniverse, 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).

Physics-guided contrastive temporal graph learning for anomaly detection and root-cause localization in industrial control systems. [PDF]

open access: yesSci Rep
Industrial control systems generate complex multivariate time series and detecting anomalies without labelled attacks is still difficult. In this work we propose a physics guided contrastive temporal graph learning framework for anomaly detection and ...

Using a nested anomaly detection machine learning algorithm to study the neutral triple gauge couplings at an e+e− collider

open access: yesNuclear Physics B, 2022
Anomaly detection algorithms have been proved to be useful in the search of new physics beyond the Standard Model. However, a prerequisite for using an anomaly detection algorithm is that the signal to be sought is indeed anomalous.

Improving Variational Autoencoders for New Physics Detection at the LHC With Normalizing Flows

open access: yesFrontiers in Big Data, 2022
We investigate how to improve new physics detection strategies exploiting variational autoencoders and normalizing flows for anomaly detection at the Large Hadron Collider. As a working example, we consider the DarkMachines challenge dataset. We show how

Quasi anomalous knowledge: searching for new physics with embedded knowledge

open access: yesJournal of High Energy Physics, 2021
Discoveries of new phenomena often involve a dedicated search for a hypothetical physics signature. Recently, novel deep learning techniques have emerged for anomaly detection in the absence of a signal prior.

Interpreting electroweak precision data including the W-mass CDF anomaly

open access: yesJournal 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.
