Accidentally light scalars from large representations
Felix Brümmer, Giacomo Ferrante, Michele Frigerio +1
In models with spontaneous symmetry breaking by scalar fields in large group representations, we observe that some of the scalar masses can be loop-suppressed with respect to the n…
Dark matter from the centre of SU(N)
Michele Frigerio, Nicolas Grimbaum-Yamamoto, Thomas Hambye
A dark sector with non-abelian gauge symmetry provides a sound framework to justify stable dark matter (DM) candidates. We consider scalar fields charged under a gauge grou…
Holographic models of composite Higgs in the Veneziano limit. Part II. Fermionic sector
Daniel Elander, Michele Frigerio, Marc Knecht +1
We continue our study of strongly-coupled, approximately scale-invariant gauge theories with a large number of flavours, which provide a suitable ultraviolet completion of the comp…
Effective comparison of neutrino-mass models
Rupert Coy, Michele Frigerio
New physics in the lepton sector may account for neutrino masses, affect electroweak precision observables, induce charged-lepton flavour violation, and shift dipole moments. The l…
Holographic models of composite Higgs in the Veneziano limit. Part I. Bosonic sector
Daniel Elander, Michele Frigerio, Marc Knecht +1
We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable…
New physics in transitions at one loop
Rupert Coy, Michele Frigerio, Federico Mescia +1
We investigate new-physics contributions to transitions in the context of an effective field theory extension of the Standard Model, including operator mixing at…
