The nonzero neutrino masses open the door for neutrino electromagnetic interactions. We study how these interactions may manifest themselves in elastic neutrino-nucleus scattering processes. Following our approach developed for the case of elastic neutrino-electron and neutrino-proton collisions, in our formalism we account for possible electromagnetic form factors of massive neutrinos: the charge, magnetic, electric, and anapole form factors of both diagonal and transition types. We give an illustration of how a nonzero neutrino millicharge can influence the differential cross section of elastic neutrino scattering on a spin-0 nuclear target.

“…; or a tool for studying fundamental interactions of neutrinos: in this work, the contribution of the neutrino electromagnetic properties is in focus. The latter neutrino properties emerge in different extensions of the Standard Model, and they include [6]: millicharges and charge radii, electric, magnetic and anapole moments.…”

The supernova neutrino flavor evolution in the presence of the non-trivial neutrino magnetic moment and strong magnetic field is numerically derived using the two-flavor and single-angle approximation. The novel properties of collective neutrino oscillations are studied and distinct patterns of flavor and spin-flavor spectral splits are presented. Finally we also discuss how the neutrino magnetic moment affects the observable supernova neutrino energy spectra.

“…1, the coupling between neutrinos and photon arises at the quantum level from loop diagrams. The general expression for the electromagnetic form factors of a massive neutrino is as follows [44][45][46][47] Γ µ (q) = eF 1 (q 2 )γ µ + ie 2m ν F 2 (q 2 )σ µν q ν + e 2m ν F 3 (q 2 )γ 5 σ µν q ν + eF 4 (q 2 )γ 5 γ µ − q /q µ q 2 , ( where q µ is the photon momentum, and F i (q 2 ), , i = 1, 2, 3, 4 are the electromagnetic form factors of the neutrino. In this analysis, we are interested in the anomalous magnetic moment (AMM) and the electric dipole moment (EDM) of the neutrino, which are defined in terms of the F 2 and F 3 form factors at q 2 = 0 as follows:…”

The stellar energy-loss rates Q due to the production of neutrino pair in the framework of 3-3-1 models are presented. The energy loss rate Q is evaluated for different values of3 in which β is a parameter used to define the charge operator in the 3-3-1 models. The correction to the rate which is compared with that of the Standard Model (δQ) is also evaluated. We show that the correction does not exceed 14% and gets the highest withThe contribution of dipole moment to the energy loss rate is small compared to the contribution of new natural gauge boson Z and this sets constraints for the mass of Z' m Z ≤ 4000GeV. This mass range is within the searching range for Z boson at LHC.
