“…The development of our knowledge about neutrino masses and mixing [1][2][3] provides a basis for exploring neutrino properties and interactions beyond the standard model (BSM). In this respect, the study of nonvanishing electromagnetic characteristics of massive neutrinos is of particular interest [4][5][6]. It can help not only to shed light on whether neutrinos are Dirac or Majorana particles, but also to constrain the existing BSM theories and/or to hint at new physics.…”

A thorough account of electromagnetic interactions of massive neutrinos in the theoretical formulation of low-energy elastic neutrino-electron scattering is given. The formalism of neutrino charge, magnetic, electric, and anapole form factors defined as matrices in the mass basis is employed under the assumption of three-neutrino mixing. The flavor change of neutrinos traveling from the source to the detector is taken into account and the role of the source-detector distance is inspected. The effects of neutrino flavor-transition millicharges and charge radii in the scattering experiments are pointed out.

“…However, another strong bound on neutrino transition magnetic moment was obtained in the presence of non-standard neutrino-nucleus interactions by Papoulias and Kosmas [39]. Detailed discussion on neutrino magnetic moment is also given elsewhere [40][41][42][43][44][45]. In additon to the konowledge about neutrino magnetic moment, the thorough information of solar magnetic fields is needed for the SFP analysis in the Sun.…”

Combined Effect of NSI and SFP on Solar Electron Neutrino Oscillation

The combined effect of Spin Flavor Precession (SFP) and the non standard neutrino interaction (NSI) on the survival probability of solar electron neutrinos (assumed to be Dirac particles) is examined for various values of ǫ11, ǫ12 and µB. It is found that the neutrino survival probability curves affected by SFP and NSI effects individually for some values of the parameters (ǫ11, ǫ12 and µB) get close to the standard MSW curve when both effects are combined. Therefore, the combined effect of SFP and NSI needs to be taken into account when the solar electron neutrino data obtained by low energy solar neutrino experiments is investigated.

Abstract. We calculate the neutrino luminosity of a degenerate electron gas in a strong magnetic field via plasmon decay to a neutrino pair due to neutrino electromagnetic moments and obtain the relative upper bounds on the effective neutrino magnetic moment.1. Neutrino emission is the main mechanism of the energy losses of stars in the late stages of their evolution [1]. We will consider cooling of the outer regions of neutron stars that are rarefied enough to be transparent to originating neutrinos. Strong magnetic fields (H > ∼ 10 12 G) can exist in these regions; moreover, the fields for the class of the neutron stars that are called magnetars can reach 10 14 − 10 16 G [2] (see also [3]). Under these conditions, the main processes of neutrino production are annihilation of an electron-positron pair (e − e + → νν), photoproduction of a neutrino pair on the electron (γe ± → e ± νν), photon decay (γ → νν) , and two-photon annihilation (γγ → νν). The results of the study of these processes (without a magnetic field) were given in the review [4]. The luminosity of a degenerate nonrelativistic gas via photoproduction of neutrino pairs for the case of a superstrong magnetic field was calculated in [5]. The authors of [6] estimated the luminosity of the degenerate electron gas due to these processes in a superstrong field. The results for photoproduction of neutrino pairs were corrected in [7].Simple extension of the standard model of the electroweak interactions generates electromagnetic dipole moments of a massive Dirac neutrino (see [1] and a recent review [8])).2. In this report, we address one of the processes of neutrino emission that is plasmon decay to a neutrino pair mediated by the neutrino electromagnetic moments. As is well known, the plasmon is the photon with a nonzero mass generated by interaction with a medium. A relevant medium model for the outer region of the neutron star is a degenerate electron gas in a strong magnetic field H:a
