The Silence of the Dipoles: Accidental Symmetries in Lepton Flavor

This paper demonstrates that models of Strongly Interacting Light Higgs with partial compositeness can evade stringent constraints from μ→eγ\mu\to e\gamma and electron EDM measurements by invoking accidental U(3)U(3) or U(2)×U(1)U(2)\times U(1) symmetries, thereby allowing the compositeness scale to reside in the few-TeV range and making it accessible to upcoming charged lepton flavor violation experiments and collider searches.

pyAmpliCol: fast tree-level matrix elements

The paper introduces pyAmpliCol, a fast public generator that extends the practical reach of colour-resolved tree-level matrix elements to higher multiplicities by utilizing a symmetric group fast Fourier transform to efficiently compute exact full-colour results, thereby bridging high-multiplicity calculations with event generation, merging, and precision applications.

Observational Signatures of Dyonic Black Holes in Non-Linear Electrodynamics

This paper investigates the observational signatures of dyonic black holes in non-linear electrodynamics, demonstrating that their modified geometry leads to smaller ISCO radii and higher effective temperatures compared to standard solutions, while statistical analysis of Event Horizon Telescope data confirms that these models provide a good fit for the observed properties of Sagittarius A*.
