![]() nu.//sub >//sub e//sub =///sub e//sub =/<6 x 10/sup -12/.mu./sub B/, providing an independent supplementary bound. The absence of such events imposes the upper bound. The data analysis accounts for this anomaly by introducing two extra phenomenological t parameters resulting in a best t of m2 1.9 3.4 2.2eV2 which is used to derive a neutrino mass limit. From the supernova 1987A up to 100 neutrinos from this additional output should have been detected in the Kamiokande II detector. We calculate the spectra of the emitted neutrinos and the associated lepton-number decrease. Search 206,651,241 papers from all fields of science. nu./sub e/ ''collapse burst.'' This also reduces the trapped lepton number of the collapsing star. The combined number of events expected at LEP due to a neutrino magnetic moment is - 'Bounding the tau neutrino magnetic moment from single photon searches at LEP' Skip to search form Skip to main content Skip to account menu. The discussion is centered around the idea of detecting an upscattering event mediated by a transition magnetic moment in a neutrino or dark matter experiment. 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. >10/sup more ยป -13/.mu./sub B/ the coherently enhanced dipole scattering on the large nuclei in a collapsing star would flip the trapped left-handed neutrinos into right-handed ones, which would escape in a highly energetic prebounce. The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol n. Neutrino Magnetic Moment (NMM) is one of the key neutrinos property since it would allow to disentangled the still unknown Majorana or Dirac neutrinos. The existence of a neutrino magnetic moment implies contributions to the neutrino mass via radiative corrections. a is the eective neutrino magnetic moment for the incoming neutrino of avor a 12, 13 ( a)2 X b ba + ba 2. ![]() We find two independent new upper bounds of 1.5 x 10/sup -12/.mu./sub B/ and 6 x 10/sup -12/.mu./sub B/ on the dipole moment of electron neutrinos, improving the existing bounds by one to two orders of magnitude and ruling out the proposed solar-neutrino effect. 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. The particle physics aspects of the neutrino electromagnetic interactions are. Here we give a detailed analysis of their implications for a stellar collapse. Finite neutrino magnetic moments are consequences of nonzero neutrino masses. Certain values were recently proposed to explain the time variation in the detected solar-neutrino flux and an extragalactic background of ionizing radiation. of the bulk neutrino, there is a magnetic moment connecting the brane neutrinos with the bulk B modes 5. ![]() Magnetic or electric dipole moments of neutrinos are indicators for possible extensions of the standard weak-interaction model. This may lead to various consequences for supernova physics. ![]()
