Singlets in Composite Higgs Models in light of the LHC di-photon searches
Alexander Belyaev, Giacomo Cacciapaglia, Haiying Cai +3
Models of compositeness can successfully address the origin of the Higgs boson, as a pseudo Nambu Goldstone boson (pNGB) of a spontaneously broken global symmetry, and flavour phys…
Light 't Hooft Top Partners
Giacomo Cacciapaglia, Alberto Parolini
Vector-like quarks, usually dubbed top partners, are a common presence in composite Higgs models. Being composite objects, their mass is expected to be of the order of their invers…
Extended Skyrme Equation of State in asymmetric nuclear matter
D. Davesne, A. Pastore, J. Navarro
We present a new equation of state for infinite systems (symmetric, asymmetric and neutron matter) based on an extended Skyrme functional constrained by microscopic Brueckner-Bethe…
Fundamental Composite 2HDM: SU(N) with 4 flavours
Teng Ma, Giacomo Cacciapaglia
We present a new model of composite Higgs based on a gauged SU(N) group with 4 Dirac fermions in the fundamental representation. At low energy, the model has a global symmetry SU(4…
Probing the Moduli Dependence of Refined Topological Amplitudes
Ignatios Antoniadis, Ioannis Florakis, Stefan Hohenegger +2
With the aim of providing a worldsheet description of the refined topological string, we continue the study of a particular class of higher derivative couplings in the ty…
Unitarity implications of diboson resonance in the TeV region for Higgs physics
Giacomo Cacciapaglia, Mads T. Frandsen
We investigate the implications of a putative new resonance in the TeV region coupled to the weak bosons. By studying perturbative unitarity in longitudinal WW scattering, we find…
