“…Under the assumption that θ 13 ¼ 0, the form of the effective magnetic moment for the MSW oscillation solution has been investigated in [5,31]. The analysis of Majorana transition neutrino magnetic moments taking into account the nonzero value of the angle θ 13 was first performed in [32]. In the general case the expression for the effective magnetic moment in the mass eigenstate basis will have a complex form consisting of interference terms ∝ μ jk μ ik .…”

A search for the solar neutrino effective magnetic moment has been performed using data from 1291.5 days exposure during the second phase of the Borexino experiment. No significant deviations from the expected shape of the electron recoil spectrum from solar neutrinos have been found, and a new upper limit on the effective neutrino magnetic moment of μ eff ν < 2.8 × 10 −11 μ B at 90% C.L. has been set using constraints on the sum of the solar neutrino fluxes implied by the radiochemical gallium experiments. Using the limit for the effective neutrino moment, new limits for the magnetic moments of the neutrino flavor states, and for the elements of the neutrino magnetic moments matrix for Dirac and Majorana neutrinos, are derived.

“…(1), which after electroweak symmetry breaking (EWSB) generate mixing of N with the SM neutrinos. Through the operators O i N B and O i N W this mixing would induce magnetic moments for the SM neutrinos, which are strongly constrained by reactor, accelerator and solar neutrino data [30,31]. This is entirely due to the missing t-channel mass suppression of the photon exchange.…”

Higgs phenomenology as a probe of sterile neutrinos

Physics beyond the Standard Model can manifest itself as both new light states and heavy degrees of freedom. In this paper, we assume that the former comprise only a sterile neutrino, N . Therefore, the most agnostic description of the new physics is given by an effective field theory built upon the Standard Model fields as well as N . We show that Higgs phenomenology provides a sensitive and potentially crucial tool to constrain effective gauge interactions of sterile neutrinos, not yet probed by current experiments. In parallel, this motivates a range of new Higgs decay channels with clean signatures as candidates for the next LHC runs, including h → γ + p miss T and h → γγ + p miss T .

“…Particularly, in the light of future experiments for coherent neutrino-nucleus scattering, which are expected to improve all bounds on neutrino electromagnetic properties [28]. Particularly, and despite perturbativity could be in conflict with lower values of the natural VEV v 2 , the neutrino specific model would be a significant benchmark to introduce these effects of new physics, at the same time that neutrino masses are at one viable scale.…”

“…Constraints over neutrino MDMs are a result of scattering experiments (based on mainly on the distortion of the recoil of charged leptons energy spectrum) [28]. In these experiments, the flavor neutrino produced at some distance from the detector is a superposition of neutrino mass eigenstates.…”

In several frameworks for leptons-sectors of two Higgs doublet models, we calculate the magnetic dipole moment for the different flavor types of neutrino. Computations are carried out by assuming a normal hierarchy for neutrino masses, and analyzing the process ν → νγ with a charged Higgs boson into the loop. The analysis was performed by sweeping the charged Higgs mass and taking into account the experimental constraints for relevant parameters in Two Higgs Doublet Models with and without flavor changing neutral currents; obtaining magnetic dipole moments close to the experimental thresholds for tau neutrinos in type II and Lepton-specific cases. In the neutrinospecific scenario, the contribution of new physics could be sizeable to the current measurement for flavor magnetic dipole moment. This fact leads to excluding possible zones in the parameter space of charged Higgs mass and vacuum expectation value of the second doublet.
