“…It is necessary to point out that there is a real interest in the development of low-threshold technology in the context of dark matter searches and the study of neutrino interactions. The silicon cryogenic detectors, the high purity germanium detectors [20], the semiconductor detectors [21] and the bolometers [22] are worth mentioning. The two experiments aiming at the measurement of recoil electron scattering angle and of azimuthal angle, i. e. Hellaz [23] and Heron [24], have also been proposed.…”

In this paper, we show how a presence of the exotic scalar, tensor weak interactions in addition to the standard vector-axial (V-A) one may help to distinguish the Dirac from Majorana neutrinos in the elastic scattering of (anti)neutrino beam off the unpolarized electrons in the limit of vanishing (anti)neutrino mass. We assume that the incoming (anti)neutrino beam comes from the polarized muon decay at rest and is the left-right chiral mixture with assigned direction of the transversal spin polarization with respect to the production plane. We display that the azimuthal asymmetry in the angular distribution of recoil electrons is generated by the interference terms between the standard and exotic couplings, which are proportional to the transversal (anti)neutrino spin polarization and independent of the neutrino mass. This asymmetry for the Majorana neutrinos is distinct from the one for the Dirac neutrinos through the absence of interference between the standard and tensor couplings. Additionally, the interference term between the standard and scalar coupling of the only left chiral neutrinos, absent in the Dirac case, appears. We also indicate the possibility of utilizing the azimuthal asymmetry measurements to search for the new CPviolating phases. Our analysis is model-independent and consistent with the current upper limits on the non-standard couplings.

In the scientific literature, a great deal of attention is paid to building the mathematical models of electromagnetic fields in composite materials in a homogeneous environment which contains a large number of small heterogeneities of different shapes and material compositions [1].Such models are reduced to solving boundary value problems for differential equations Maxwell with special kinds of particular boundary conditions on the structures of composite materials.In this context one of the important structures is the spatial screen and environment which is to simulate the actual boundary conditions pairing them [2][3][4][5][6]. Such models provide a mathematical foundation for solving problems of electromagnetic-field shielding composite screens, that are used to solve problems of electromagnetic compatibility of technical equipment in radio and electronics.
