Impact of Higgs precision measurements at the LHC and FCC-ee on the spectrum of composite Higgs models
Reza Asgharzadeh Jelodar, Kazem Bitaghsir Fadafan, Giacomo Cacciapaglia
We investigate the minimal composite Higgs model based on the symmetry-breaking pattern , where electroweak symmetry breaking is governed b…
Perusing confining pseudoreal theories: a story of emerging massless spin-1 bosons
Giacomo Cacciapaglia, Konstantinos Kollias
Solving quantum field theory, which is at the basis of the standard model of particle interactions, is one of the main tasks of contemporary theoretical physics. Minimal asymptotic…
When Black Holes Can Wear Pants
Giacomo Cacciapaglia, Manuel Del Piano, Francesco Sannino +1
We investigate the conditions under which black hole fragmentation, the splitting of a black hole horizon into multiple smaller ones, may occur. The simplest realization is that of…
Heavy Axion from a Confining Mirror GUT
Giacomo Cacciapaglia, Csaba Csáki, Teng Ma
We propose a new framework for solving the strong CP problem via a heavy axion, using mirror symmetry and grand unification. The mirror GUT sector remains unbroken and dynamically…
Completely asymptotically free chiral theories with scalars
Giacomo Cacciapaglia, Francesco Sannino, Sophie Wagner
We provide the conditions for complete asymptotic freedom for chiral gauge theories including scalars, as motivated by grand unified models. These are generalised Georgi-Glashow an…
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…
