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 ...

Solutions to the MiniBooNE Anomaly from New Physics in Charged Meson Decays. [PDF]
Physical Review Letters, 2021 We point out that production of new bosons by charged meson decays can greatly enhance the sensitivity of beam-focused accelerator-based experiments to new physics signals. This enhancement arises since the charged mesons are focused and their three-body

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.

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.

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.

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.

Anomaly Detection for Physics Analysis and Less Than Supervised Learning [PDF]
Artificial Intelligence for High Energy Physics, 2020 Modern machine learning tools offer exciting possibilities to qualitatively change the paradigm for new particle searches. In particular, new methods can broaden the search program by gaining sensitivity to unforeseen scenarios by learning directly from ...
