	Title	Naturally light neutrinos in Diracon model			Type	Journal Article
	Year	2016	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	762	Issue		Pages	162-165
	Keywords
	Abstract	We propose a simple model for Dirac neutrinos where the smallness of neutrino mass follows from a parameter kappa whose absence enhances the symmetry of the theory. Symmetry breaking is performed in a two-doublet Higgs sector supplemented by a gauge singlet scalar, realizing an accidental global U(1) symmetry. Its spontaneous breaking at the few TeV scale leads to a physical Nambu -Goldstone – boson the Diracon, denoted D – which is restricted by astrophysics and induces invisible Higgs decays such as h -> DD. The scheme provides a rich, yet very simple scenario for symmetry breaking studies at colliders such as the LHC.
