Gravitational Axial Anomaly for Four Dimensional Conformal Field Theories [PDF]
, 1999 We construct the three point function involving an axial vector current and two energy-momentum tensors for four dimensional conformal field theories. Conformal symmetry determines the form of this three point function uniquely up to a constant factor if

Particle physics models for the 17 MeV anomaly in beryllium nuclear decays [PDF]
, 2016 The $6.8\ensuremath{\sigma}$ anomaly in excited $^{8}\mathrm{Be}$ nuclear decays via internal pair creation is fit well by a new particle interpretation.

Axial anomaly: the modern status
, 2006 The modern status of the problem of axial anomaly in QED and QCD is reviewed. Two methods of the derivation of the axial anomaly are presented: 1) by splitting of coordinates in the expression for the axial current and 2) by calculation of triangle ...

Nuclear Physics B, 2022 The muon magnetic anomaly, aμ=(gμ−2)/2, plays a special role in the history of the Standard Model (SM). Precise calculations and measurements of this fundamental quantity provide a stringent test of the SM and a window to the physics beyond.

International Journal of Adaptive Control and Signal Processing, EarlyView.Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Implications of flavour anomalies for new physics [PDF]
Proceedings of Corfu Summer Institute 2017 "Schools and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2017), 2018 We discuss the observed deviations in $b \to s \ell^+ \ell^-$ processes from the Standard Model predictions and present global fits for both hadronic effects and the New Physics description of these anomalies. We investigate whether the different anomalies can be described by a consistent New Physics effect.

LHCb anomaly and B physics in flavored Z ' models with flavored Higgs doublets [PDF]
, 2017 We study an extended Standard Model with a gauged U(1)$^{\prime}$ flavor symmetry, motivated not only by the fermion mass hierarchy but also by the excesses in $B \to K^{(*)} l l$ reported by the LHCb collaborations.

Mixed modulus and anomaly mediation in light of the muon g − 2 anomaly
Journal of High Energy Physics, 2021 The new measurement of the anomalous magnetic moment of muon at the Fermilab Muon g − 2 experiment has strengthened the significance of the discrepancy between the standard model prediction and the experimental observation from the BNL measurement.

Advanced Engineering Materials, EarlyView.This article presents a comprehensive analysis of the intrinsic relationships and applicability of Hill48 yield criterion. The applicability and error evaluation conditions for Hill48 are established based on specific experimental data. A parameter calibration strategy for N‐value based on error minimization is proposed, and the predictive accuracy is ...
