Stellar cooling limits on KK gravitons and dark dimensions
Edward Hardy, Anton Sokolov, Henry Stubbs
We revisit cooling bounds on light Kaluza-Klein (KK) gravitons, as arise in the dark dimension scenario, considering red giants, neutron stars, and supernovae. In addition to brems…
Searching for GUT-scale QCD Axions and Monopoles with a High Voltage Capacitor
Michael E. Tobar, Anton V. Sokolov, Andreas Ringwald +1
The QCD axion has been postulated to exist because it solves the strong CP problem. Furthermore, if it exists axions should be created in the early Universe and could account for a…
Electromagnetic Couplings of Axions
Anton V. Sokolov, Andreas Ringwald
We show that, contrary to assertions in the literature, the main contribution to the axion-photon coupling need not be quantized in the units proportional to . In particular,…
Duality Symmetric Electrodynamics in Curved Spacetime
Anton V. Sokolov
We derive Maxwell equations for electric and magnetic fields in curved spacetime from first principles, relaxing an unnecessary assumption on the structure of the four-potential in…
Magnetic anomaly coefficients for QCD axion couplings
Anton V. Sokolov, Andreas Ringwald
We argue that there are both experimental and theoretical reasons to reconsider the construction of KSVZ-like axion models. From the experimental side, predictions for the axion-ph…
Photophilic hadronic axion from heavy magnetic monopoles
Anton V. Sokolov, Andreas Ringwald
We propose a model for the QCD axion which is realized through a coupling of the Peccei-Quinn scalar field to magnetically charged fermions at high energies. We show that the axion…
Reconciling hints on axion-like-particles from high-energy gamma rays with stellar bounds
Gautham Adamane Pallathadka, Francesca Calore, Pierluca Carenza +9
It has been recently claimed by two different groups that the spectral modulation observed in gamma rays from Galactic pulsars and supernova remnants can be due to conversion of ph…
Possibility of hypothetical stable micro black hole production at future 100 TeV collider
Anton V. Sokolov, Maxim S. Pshirkov
We study the phenomenology of TeV-scale black holes predicted in theories with large extra dimensions, under the further assumption that they are absolutely stable. Our goal is to…
