Composite top partners in exotic colour representations
Giacomo Cacciapaglia, Rosy Caliri, Aldo Deandrea +5
Composite Higgs models with partial compositeness generically predict coloured fermionic resonances associated with the strong dynamics responsible for electroweak symmetry breakin…
Multi-boson splashes at future colliders from electroweak compositeness
G. Cacciapaglia, A. Deandrea, A. M. Iyer +2
We propose a new collider signature for the composite origin of the electroweak symmetry breaking of the standard model. The Higgs sector consists of new fundamental fermions (hype…
Electroweak precision tests for asymptotic Grand Unification models
Giacomo Cacciapaglia, Aldo Deandrea, Christian Verollet
Asymptotic grand unification is an alternative framework to traditional quantitative unification, as the renormalisation flow leads towards an ultra-violet safe fixed point. Phenom…
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…
Leptogenesis in five-dimensional asymptotic Grand Unification models
Timothe Alezraa, Giacomo Cacciapaglia, Aldo Deandrea
Asymptotic grand unification models can be constructed in five dimensions compactified on an orbifold. We demonstrate that the parameter space of such models admit solutions that n…
