Higgs physics confronts the MW anomaly
Physics 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.

Quantum anomaly detection for collider physics
Journal of High Energy Physics, 2023 We explore the use of Quantum Machine Learning (QML) for anomaly detection at the Large Hadron Collider (LHC). In particular, we explore a semi-supervised approach in the four-lepton final state where simulations are reliable enough for a direct ...

New Physics Suggested by Atomki Anomaly [PDF]
Frontiers in Physics, 2019 We consider several extensions of the Standard Model (SM) which can explain the anomalies observed by the Atomki collaboration in the decay of excited states of Beryllium via a new boson with a mass around 17 MeV yielding e+e− pairs.

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

Nuclear 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
Frontiers 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

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

Recent anomalies in B physics [PDF]
Science Bulletin, 2018 $B$ physics plays important roles in searching for the new physics (NP) beyond the standard model (SM). Recently, some deviations between experimental data and SM predictions were reported, namely $R(D^{(*)})$, $P_5^\prime$ and $R_{K^{(*)}}$ anomalies.

Minor Physical Anomalies in Schizophrenia [PDF]
Schizophrenia Bulletin, 1989 This study was conducted to investigate the value of using physical anomalies (PAs) to evaluate early prenatal injury in schizophrenia. PAs are minor abnormalities in development of the head, hands, and feet that are presumably associated with insult during the first trimester.

Quasi anomalous knowledge: searching for new physics with embedded knowledge
Journal 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.
