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…
Strong CP problem with low-energy emergent QCD: The 4321 case
Javier Fuentes-Martin, Mario Reig, Avelino Vicente
We analyze the strong CP problem and the implications for axion physics in the context of vector leptoquark models, recently put forward as an elegant solution to the hints o…
SO(3) family symmetry and axions
Mario Reig
Motivated by the idea of Comprehensive Unification, we consider a gauged flavor extension of the Standard Model, including right-handed neutrinos and a Peccei-Quinn symmetr…
Cosmic implications of a low-scale solution to the axion domain wall problem
Andrea Caputo, Mario Reig
The post-inflationary breaking of Peccei-Quinn (PQ) symmetry can lead to the cosmic domain wall catastrophe. In this Letter we show how to avoid domain walls implementing the Insta…
Light majoron cold dark matter from topological defects and the formation of boson stars
Mario Reig, José W. F. Valle, Masaki Yamada
We show that for a relatively light majoron ( eV) non-thermal production from topological defects is an efficient production mechanism. Taking the type I seesaw as benchm…
On the high-scale instanton interference effect: axion models without domain wall problem
Mario Reig
We show that a new chiral, confining interaction can be used to break Peccei-Quinn symmetry dynamically and solve the domain wall problem, simultaneously. The resulting theory is a…
