Dirac neutrinos from Peccei-Quinn symmetry: a fresh look at the axion
Eduardo Peinado, Mario Reig, Rahul Srivastava +1
We show that a very simple solution to the strong CP problem naturally leads to Dirac neutrinos. Small effective neutrino masses emerge from a type I Dirac seesaw mechanism. Neutri…
Gravitational footprints of massive neutrinos and lepton number breaking
Andrea Addazi, Antonino Marcianò, António P. Morais +3
We investigate the production of primordial Gravitational Waves (GWs) arising from First Order Phase Transitions (FOPTs) associated to neutrino mass generation in the context of ty…
A theory for scotogenic dark matter stabilised by residual gauge symmetry
Julio Leite, Oleg Popov, Rahul Srivastava +1
Dark matter stability can result from a residual matter-parity symmetry, following naturally from the spontaneous breaking of the gauge symmetry. Here we explore this idea in the c…
Systematic classification of two loop d = 4 Dirac neutrino mass models and the Diracness-dark matter stability connection
Salvador Centelles Chuliá, Ricardo Cepedello, Eduardo Peinado +1
We provide a complete systematic classification of all two-loop realizations of the dimension four operator for Dirac neutrino masses. Our classification is multi-layered, starting…
Dark matter as the origin of neutrino mass in the inverse seesaw mechanism
Sanjoy Mandal, Nicolás Rojas, Rahul Srivastava +1
We propose that neutrino masses are "seeded" by a dark sector within the inverse seesaw mechanism. This way we have a new, "hidden", variant of the scotogenic scenario for radiativ…
CP Symmetries as Guiding Posts: revamping tri-bi-maximal Mixing. Part II
Peng Chen, Salvador Centelles Chuliá, Gui-Jun Ding +2
In this follow up of arXiv:1812.04663 we analyze the generalized CP symmetries of the charged lepton mass matrix compatible with the complex version of the Tri-Bi-Maximal (TBM) lep…
