Characterization of the ^{163}Ho Electron Capture Spectrum: A Step Towards the Electron Neutrino Mass Determination.
The isotope ^{163}Ho is in many ways the best candidate to perform experiments to investigate the value of the electron neutrino mass. It undergoes an electron capture process to ^{163}Dy with an energy available to the decay, Q_{EC}, of about 2.8 keV. According to the present knowledge, this is the lowest Q_{EC} value for such transitions. Here we discuss a newly obtained spectrum of ^{163}Ho,...
متن کاملElectron-Neutrino Majorana Mass and Solar Neutrino Oscillations
Assuming the Majorana masses of νe and the linear combination cντ − sνμ to be equal from their couplings to a heavy scalar triplet ξ, I show that their radiative splitting is given by ∆m2/m2ν = (3c /4π)(GF / √ 2)m2τ ln(m 2 ξ/m 2 W ). This is applicable to the small-angle matter-enhanced oscillation solution of the solar neutrino deficit and restricts mν to be between 0.20 and 0.36 eV if c 2 = 0...
متن کاملNeutrino Mass and Magnetic Moment from Neutrino-electron Scattering
We study both the elastic (νe → νe) and the radiative process (νe → νeγ) and discuss how these processes can shed light on some current topics in neutrino physics such as a neutrino magnetic moment and neutrino oscillations. The radiative process allows to reach low values of Q without the need to operate at very small energies of recoil electrons, a favourable scenario to search for a neutrino...
متن کاملMass of Electron-Neutrino and SN1987A Data
By using a fresh analysis of SN1987A data it is shown that mass of the electron neutrino is zero. The masses of other neutrino flavors are found to be non-zero. The neutrino astrophysics has been the subject of great interest for the last many decades. Since it was postulated in 1930, the properties of neutrino and in particular the question of its mass have gained much attention on both theore...
متن کاملA combined beta-beam and electron capture neutrino experiment
The next generation of long baseline neutrino experiments will aim at determining the value of the unknown mixing angle, θ13, the type of neutrino mass hierarchy and the presence of CPviolation in the lepton sector. Beta-beams and electron capture experiments have been studied as viable candidates for long baseline experiments. They use a very clean electron neutrino beam from the β-decays or e...
