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.

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

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.

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.

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
