The Dark Side of a Tera-Z Factory
Pablo Olgoso, Paride Paradisi, Nudzeim Selimovic
The future circular collider (FCC-ee or CEPC) will provide unprecedented sensitivity to indirect new physics signals emerging as small deviations from the Standard Model p…
Anatomy and Phenomenology of Minimal Flavor Deconstruction in the Lepton Sector
Antonio Masiero, Paride Paradisi, Daniel Quieroz +3
We investigate the low-energy phenomenology of a minimal flavor-deconstructed framework in the lepton sector within an effective field theory approach, focusing on the interplay be…
Amplitudes and partial wave unitarity bounds
Luigi C. Bresciani, Gabriele Levati, Paride Paradisi
We develop a formalism, based on spinor-helicity techniques, to generalize the formulation of partial wave unitarity bounds. We discuss unitarity bounds for (with $N,M \g…
Probing lepton dipole moments at future Lepton Colliders
Dario Buttazzo, Gabriele Levati, Yang Ma +3
The electric and magnetic dipole moments of the electron and of the muon provide stringent tests of the Standard Model and sensitive probes of new physics. By contrast, the corresp…
Hunting for a 17 MeV particle coupled to electrons
Luca Di Luzio, Paride Paradisi, Nudzeim Selimovic
We discuss a set of precision observables that can probe the existence of a light particle coupled to electrons in the mass range of 1-100 MeV. As a case study, we consider the…
Anarchic neutrinos from flavor deconstruction: phenomenology of the lepton sector
Gino Isidori, Paride Paradisi, Andrea Sainaghi +1
We investigate the neutrino sector in the framework of flavor deconstruction with an inverse-seesaw realization. This setup naturally links the hierarchical charged-fermion masses…
