“…Due to the ALPs mass is very low and only protected by the U(1) A symmetry which is explicitly broken by gravity effects, the Z N symmetry will have a high order. This fact also happens in models with QCD axions and it is shared by all models with this type of stabilization mechanism [23,40,43,44,49,66].…”

“…In particular, with the aim of generating neutrino masses the authors in Refs. [23,40] used these types of discrete gauge symmetries in order to protect the associated lepton-number-breaking scale. In this work, we go further by building a self-consistent framework of ALPs DM[50] and neutrino masses via the ISS mechanism [51,52].…”

We present a framework linking axionlike particles (ALPs) to neutrino masses through the minimal inverse seesaw (ISS) mechanism in order to explain the dark matter (DM) puzzle. Specifically, we explore three minimal ISS cases where mass scales are generated through gravity-induced operators involving a scalar field hosting ALPs. In all of these cases, we find gravity-stable models providing the observed DM relic density and, simultaneously, consistent with the phenomenology of neutrinos and ALPs. Remarkably, in one of the ISS cases, the DM can be made of ALPs and sterile neutrinos. Furthermore, other considered ISS cases have ALPs with parameters inside regions to be explored by proposed ALPs experiments.Comment: 1 figure, 14 page

Erratum to: JHEP05(2015)069ArXiv ePrint: 1503.03502The two models containing two ALPs in section 2.3 of ref.[1] lead to too light non-SM charged leptons E of only a few GeV. (The single ALP model of section 2.2 does not suffer from this problem.)This problem can be amended without significant modifications by considering two heavy vector-like fermions E and E ′ instead of one. Instead of the last two terms of eq. (2.40), (2.41) and (2.47) of [1], we should consider the four termswhere we already fixed the r, r ′ powers without affecting any formula. One should use s = s ′ = 1 if needed. Now the heavy leptons E, E ′ have intermediate scale masses of order 10 9÷10 GeV. The charge of the discrete symmetries are only modified for E L,R and E ′ L,R in a predictable manner; see table below. Appropriate normalization of these charges leads to the PQ charges X, X ′ and the extended lepton numbers L, L ′ . Note that U(1) X [U(1) X ′ ] is vectorial for E ′ (E) and that the first two terms of the Lagrangian above implies E R and E ′ R have equal charges (X, X ′ , Z, Z ′ , L, L ′ ). The rest of the formulas and the phenomenological consequences remain unchanged.Additionally, the lowest order operator couplingL-S R for model II isLHS R σ 4 σ ′ instead ofLHS R σ 2 σ ′ * . This implies m DS is negligible in eq. (2.52).

We present a minimal extension of the Standard Model (SM) providing a consistent picture of particle physics from the electroweak scale to the Planck scale and of cosmology from inflation until today. Three right-handed neutrinos N i , a new color triplet Q and a complex SM-singlet scalar σ, whose vacuum expectation value v σ ∼ 10 11 GeV breaks lepton number and a Peccei-Quinn symmetry simultaneously, are added to the SM. At low energies, the model reduces to the SM, augmented by seesaw generated neutrino masses and mixing, plus the axion. The latter solves the strong CP problem and accounts for the cold dark matter in the Universe. The inflaton is comprised by a mixture of σ and the SM Higgs, and reheating of the Universe after inflation proceeds via the Higgs portal. Baryogenesis occurs via thermal leptogenesis. Thus, five fundamental problems of particle physics and cosmology are solved at one stroke in this unified Standard Model -Axion -seesawHiggs portal inflation (SMASH) model. It can be probed decisively by upcoming cosmic microwave background and axion dark matter experiments.
