Looking for axions in exotic, highly magnetised White Dwarf stars [PDF]
openThe Peccei-Quinn (PQ) symmetry is a potential extension of the Standard Model that offers a compelling solution to the strong CP problem. This symmetry predicts the existence of a new pseudoscalar particle, the QCD axion, which, along with more ...

Axion-like Particles from String Compactifications
, 2013 We review how axion-like particles (ALPs) naturally emerge in the low-energy effective field theory of string compactifications. We focus on the study of their mass spectrum and couplings, stressing that they depend on the mechanism used to fix the ...

A comprehensive study of ALPs from B-decays
Journal of High Energy PhysicsWe present a comprehensive study of axion-like particles (ALPs) through flavor changing neutral current processes, such as B → Ka followed by a → hadronic, γγ, μ + μ − channels. Our generic framework encompasses different ultraviolet scenarios similar to

Plant Biology, EarlyView.Balkan high‐mountain fens harbour unique endemic plant communities, with a west‐to‐east compositional gradient and local richness primarily shaped by palaeoclimate. As these fens have already experienced drier, warmer summers than at present, they may withstand climate change if actively and effectively protected. Abstract The phenomenon of Balkan high‐

Sensitivity of the CUPID Experiment to Bragg-Primakoff Conversion of Solar Axions and ALPs [PDF]
, 2023 The author reports in this dissertation on the application of a technique to use bolometer detector arrays, such as those of the CUORE experiment and its proposed upgrade CUPID, to search for 14.4 keV Solar axions arising from an M1 nuclear transition of

High quality QCD axion via electric-magnetic duality
Journal of High Energy PhysicsWe propose a novel paradigm for the QCD axion with high-quality Peccei-Quinn (PQ) symmetry on the basis of electric-magnetic duality in the conformal window of a supersymmetric gauge theory.

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy
Sedimentology, EarlyView.ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Heavy QCD axions at high-energy muon colliders
Journal of High Energy PhysicsWe study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenology driven by the anomalous gluon aG G ~ $$ \left( aG\overset{\sim }{G ...

Energy Optimization Models for the Locomotive Assignment Problem
Networks, Volume 88, Issue 3, Page 369-390, October 2026.ABSTRACT Reducing energy consumption is a key objective in transportation. Using detailed infrastructure data, this study introduces the Green Locomotive Assignment Problem (GLAP) to minimize energy consumption in railway operations by efficiently assigning locomotives to pre‐scheduled trains.

Accidental Peccei-Quinn symmetry from gauged U(1) and a high quality axion
Journal of High Energy PhysicsWe construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model and its grand unified extensions by an anomaly-free axial U(1) a symmetry
