Phenomenology of Non-Abelian Gauge and Goldstone Bosons in a U(2) Flavor Model

Lorenzo Calibbi, Jiangyi Yi

We investigate the phenomenological implications of the bosons associated with the subgroup in a simple and realistic flavor model. While the Nambu-Goldstone bos…

ALP production in Lepton Flavour Violating meson, tau and gauge boson decays

Marco Ardu, Lorenzo Calibbi, Marco Fedele +1

In this paper we study axion-like particles (ALPs) with lepton-flavour-violating (LFV) couplings in the mass regime above the muon threshold, , where the strong bound fro…

Hunting for Neutrino Texture Zeros with Muon and Tau Flavor Violation

Lorenzo Calibbi, Xiyuan Gao, Man Yuan

We revisit the minimal type II seesaw mechanism generating the Majorana neutrino mass matrix , under the assumption that two entries of vanish. Such flavor structures…

t-channel dark matter at the LHC -- a whitepaper

Chiara Arina, Benjamin Fuks, Luca Panizzi +67

This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…

Gravitational waves from cosmic strings in Froggatt-Nielsen flavour models

Simone Blasi, Lorenzo Calibbi, Alberto Mariotti +1

Gravitational waves (GW) are a powerful probe of the earliest moments in the Universe, enabling us to test fundamental interactions at energy scales beyond the reach of laboratory…
