Sterile Neutrino Anarchy
Julian Heeck, Werner Rodejohann
Lepton mixing, which requires physics beyond the Standard Model, is surprisingly compatible with a minimal, symmetryless and unbiased approach, called anarchy. This contrasts with…
Exotic Charges, Multicomponent Dark Matter and Light Sterile Neutrinos
Julian Heeck, He Zhang
Generating small sterile neutrino masses via the same seesaw mechanism that suppresses active neutrino masses requires a specific structure in the neutral fermion mass matrix. We p…
Proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology (FLASY12)
I. de Medeiros Varzielas, C. Hambrock, G. Hiller +66
These are the proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology, held 30 June 2012 - 4 July 2012, Dortmund, Germany.
Seesaw parametrization for n right-handed neutrinos
Julian Heeck
Introducing n right-handed neutrinos to the Standard Model yields, in general, massive active neutrinos. We give explicit parametrizations for the involved mixing and coupling matr…
Vanishing Minors in the Neutrino Mass Matrix from Abelian Gauge Symmetries
Takeshi Araki, Julian Heeck, Jisuke Kubo
Augmenting the Standard Model by three right-handed neutrinos allows for an anomaly-free gauge group extension G_max = U(1)_(B-L) x U(1)_(L_e-L_mu) x U(1)_(L_mu-L_tau). While simpl…
Neutrino Hierarchies from a Gauge Symmetry
Julian Heeck, Werner Rodejohann
We consider the phenomenology of the gauged abelian symmetry B + 3 (L_e - L_mu - L_tau). Right-handed neutrinos necessary to cancel triangle anomalies are used in a type-I seesaw s…
