2/18/2023 0 Comments Neutrino magnetic momentThe neutron's magnetic moment is exploited to probe the atomic structure of materials using scattering methods and to manipulate the. The neutron interacts with normal matter through either the nuclear force or its magnetic moment. Theories beyond the Standard Model which. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments. In the standard electroweak interactions, neutrino magnetic moments are suppressed by the small neutrino masses. By contrast, weak interaction produced a negligible number of events at such low energies.Īs a result we get a Bayesian upper limit as good as 10 -11 Bohr magneton after running vIOLETA for 3 years. The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol n. A straightforward calculation of the one-loop diagram 1012,1204 (see also 1490) depicted in Fig. The transition moment, which is relevant to i j +, may exist for both Dirac and Majorana neutrinos. 5.1), only the Dirac neutrino can have a magnetic moment. In a Minimally extended SM, Majorana's neutrino has null Magnetic Moment, while in an Extended SM, it. Abstract From the general argument (see Sect. Besides, NMM strongly depends on the Beyond Standard Model (SM) scenario chosen. Thus, this channel twice the competing signal events. Neutrino Magnetic Moment (NMM) is one of the key neutrino's property since it would allow to disentangled the still unknown Majorana or Dirac neutrino's nature. It is responsible for the steps in the red curve.Īt very low energy, the CEvNS expected events are pretty similar to the one expected by background, it means a 1 kdru rate. For electron-neutrino interaction, the binding energies play a similar role to the nuclear quenching. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments. As in previous analysis, Quenching from CONNIE2019 was applied to both weak and EM interactions that produced nuclear recoils. The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol n. When all these contributions are taken into account we get the spectrum in the figure. Besides, background events were accounted for by adding a rate of 1 kdru in the full range under consideration. Thus, the events originated in the weak interaction process and CEvNS were computed. To calculate the capability of vIOLETA to constraint this quantity, we have calculated the number of events expected from all Low Energy Neutrino Interactions (LENI) accessible by this experiment. In the same way, the expected NMM for Dirac's neutrino changes five orders of magnitudes depending on the model. In a Minimally extended SM, Majorana's neutrino has null Magnetic Moment, while in an Extended SM, it can reach values as high as 10 -10 Bohr magneton. Neutrino Magnetic Moment (NMM) is one of the key neutrino's property since it would allow to disentangled the still unknown Majorana or Dirac neutrino's nature.
