The Good Qualities of the Weak Axion
Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner
The presence of a topological susceptibility in the electroweak sector of the Standard Model motivates the existence of a good quality weak axion , associated with the spontan…
Unveiling the Quantum Nature of Black Holes: Towards a Proof of Hawking Radiation through Gamma-Ray Observations
Atreya Acharyya, Giacomo Cacciapaglia, Manuel Meyer +1
Hawking's groundbreaking prediction that black holes emit thermal radiation and ultimately evaporate remains unverified due to the extreme faintness of this radiation for stellar-m…
Hiding in Plain Sight, the electroweak
Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner
The presence of a topological susceptibility in the electroweak sector of the Standard Model implies the existence of a pseudoscalar state in the spectrum, . We show that, wi…
Grand-unification Theory Atlas: Standard Model and Beyond
Giacomo Cacciapaglia, Aldo Deandrea, Konstantinos Kollias +1
Under a reasonable set of ab-initio assumptions, we define and chart the atlas of simple gauge theories with families of fermions whose masses are forbidden by gauge invariance. We…
Comment to "The asymptotically-free gauge theories"
Giacomo Cacciapaglia, Aldo Deandrea, Francesco Sannino
The recent paper "The asymptotically-free gauge theories" by Ben Gripaios and Khoi Le Nguyen Nguyen [arXiv:2507.12348] presents a proposed classification of gauge theories valid do…
Charting Standard Model Duality and its Signatures
Giacomo Cacciapaglia, Francesco Sannino
We investigate high and low energy implications of a gauge dual description of the Standard Model. The high energy electric theory features gauge dynamics involving only fermionic…
