![]() ![]() The discussion is centered around the idea of detecting an upscattering event mediated by a transition magnetic moment in a neutrino. NEUTRINO MAGNETIC MOMENT FREEEach contribution of the neutrino form factors to the neutrino mean free path is discussed. Equation (1.1) predicts that the neutrino magnetic moment is proportional to the neutrino mass m i, but the value of m i does not follow from the calculation. We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos. The decrease of the neutrino mean free path is expected to decelerate the cooling of neutron stars. ![]() The quenching of the neutrino mean free path is evaluated to be about 12-58% for the values of μ ν = 3 × 10 − 12 μ B and R ν = 3.5 × 10 − 5 MeV − 1 compared with that obtained for the μ ν = 0 and R ν = 0. a is the eective neutrino magnetic moment for the incoming neutrino of avor a 12, 13 ( a)2 X b ba + ba 2. The recent anomalous excess at few keV electronic recoils observed by the XENON1T collaboration might indicate a 2.2 × 10 11 B effective neutrino magnetic moment ( eff) from solar neutrinos. where q is the momentum transferred to the two-nucleon system the neutrino scattering angle is dened by kk kk cos in the -d center-of-mass system. Something like 10 19 times the magnetic moment of the electron. We find that the increase of the cross section relative to that without neutrino form factors results in the decrease of the neutrino mean free path when neutrino form factors and the in-medium modifications of the nucleon weak and electromagnetic form factors are simultaneously considered. Neutrino magnetic moment (MM) is an important property of massive neutrinos. Neutrinos 'do' have a magnetic moment, in the sense that the Standard Model (with minimal additions to permit the neutrino to have mass) predicts that neutrinos acquire a very, very small magnetic moment. We analyze the neutrino scattering cross section and mean free path in cold nuclear matter. Finally, we discuss model-building challenges that arise in scenarios that feature large magnetic moments while keeping neutrino masses well below 1 eV. We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to. We use a relativistic mean-field model for the in-medium effective nucleon mass and quark-meson coupling model for nucleon form factors. The magnetic dipole moment of neutrinos is modified at high temperature and. Effects of neutrino charge radius and magnetic moment constraints obtained from the astrophysical observations and reactor experiments, as well as in-medium modifications of the weak and electromagnetic nucleon form factors of the matter on the neutrino electroweak interaction with dense matter, are estimated. We recalculate the magnetic moment of neutrinos in a hot and dense medium. ![]()
