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.

Quantum anomaly detection for collider physics

open access: yesJournal 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]

open access: yesFrontiers 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.

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

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 ...

Recent anomalies in B physics [PDF]

open access: yesScience 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.

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.

Minor Physical Anomalies in Schizophrenia [PDF]

open access: yesSchizophrenia 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

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.
