Scale-independent relations between neutrino mass parameters
Mu-Chun Chen, Shaheed Perez, Michael Ratz
Theories of flavor operate at various scales. Recently it has been pointed out that in the context of modular flavor symmetries certain combinations of observables are highly const…
Effects of dark dipole radiation on eccentric supermassive black hole binary inspirals
Mu-Chun Chen, Yan Cao
The final-parsec problem has long posed a central challenge in understanding the merger of supermassive black hole binaries. In this paper, we investigate a scenario in which a dar…
INFLAVON: CMB as cosmic tracer of Flavor physics
Mu-Chun Chen, Anish Ghoshal, V. Knapp-Perez +3
We unify one of the most widely studied frameworks to explain the hierarchical structure of the flavor sector in the Standard Model, the Froggatt-Nielsen mechanism, with cosmic inf…
Gravitational Waves in an A4 Neutrino Mass Model
Mu-Chun Chen, Harold J. Matias, Cameron Moffett-Smith
The A4 flavor symmetry has provided tremendous insight into the flavor structure of the lepton sector of the Standard Model, predicting a very good approximation to neutrino mixing…
Modular Flavor Symmetries and Fermion Mass Hierarchies
Mu-Chun Chen, Xueqi Li, Xiang-Gan Liu +1
We investigate fermion mass hierarchies in models with modular flavor symmetries. Several key conclusions arise from the observation that the determinants of mass matrices transfor…
Multiple realizations of modular flavor symmetries and their phenomenology
Carlos Arriaga-Osante, Mu-Chun Chen, Ramon Diaz-Castro +4
We point out that specifying the finite modular group does not uniquely fix a modular flavor symmetry. We illustrate this using the finite modular group . Otherwise equivalent…
