The mass of the neutrino can be determined by the theoretically derived expression (m_k=\\alpha^3 m_e) (m_k is the mass of the neutrino, m_e is the mass of electron, alpha is the fine-structure constant).L. I. Orban
1. an elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 x 10−19 coulombs, and existing independently or as the component outside the nucleus of an atom. 2. a unit of charge equal to the charge on one electron. [1891; electr (ic) ...
Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass. However, the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics run of the Karlsruhe Tritium Neutrino experimen...
This is applicable to the small-angle matter-enhanced oscillation solution of the solar neutrino deficit and restricts m ν to be between 0.20 and 0.36 eV if c 2 =0.7 and m ξ =10 14 GeV. 关键词: gauge field theory at finite temperature gauge fixing Abelian projection magnetic monopoles ...
A free neutron—one that is not incorporated into a nucleus—is subject toradioactive decayof a type calledbeta decay. It breaks down into a proton, an electron, and an antineutrino (theantimattercounterpart of theneutrino, a particle with no charge and little or no mass); thehalf-lifefor...

Proposed medium-baseline reactor neutrino experiments offer unprecedented opportunities to probe, at the same time, the mass-mixing parameters which govern $ u_e$ oscillations both at short wavelength (delta m^2 and theta_{12}) and at long wavelength (Delta m^2 and theta_{13}), as well as...
The helicity of the neutrino is equal to −1. If we neglect the mass of the positron the helicity of the positron will be the same as the helicity of the antineutrino and it will be equal to +1. Thus, the projection of the total angular momentum on the direction of the momentum of...
The mass of a proton is approximately What is the change in atomic mass number when an atom emits an alpha particle? Which elementary particle has the greatest mass? What is the relative mass of an electron? Which subatomic particle has the largest mass?
