THE view has recently been put forward1 that a neutral particle of about electronic mass, and spin ½h (where h = h/2π) exists, and that this ‘neutrino’ is emitted together with an electron in β-decay. This assumption allows the conservation laws for energy and angular momentum to hold in nuclear physics2, Both the emitted electron and neutrino could be described either (a) as having existed before in the nucleus or (b) as being created at the time of emission. In a recent paper3 Fermi has… Expand
Neutrino Physics
The topics discussed in this lecture include: general prope rties of neutrinos in the SM, the theory of neutrino masses and mixings (Dirac and M ajorana), neutrino oscillations both in vacuum and inExpand

When Energy Conservation Seems to Fail: The Prediction of the Neutrino
A historical case study concerning the serious doubts that arose in early 1930s about the validity of the law of energy conservation in nuclear disintegrations, and the hypothesis of neutrino, willExpand
Neutrinos: Ghosts of creation
The magnitude of the mass of an electron neutrino is still uncertain, yet this parameter is of vital importance to our understanding of cosmology, particle physics and neutrino oscillations. TheExpand
Past Experiments Exclude Light Majorana Neutrinos
In 1937, Majorana [1] remarked that a possible variant Dirac 4-spinor states [2] of electrically neutral, spin-1/2 particles is that they are their own antiparticles, and suggested that neutrinos mayExpand
Elastic scattering of a muon neutrino by an electron in the presence of a circularly polarized laser field.
In view of the great contribution of neutrino-electron scattering to the deep understanding of electroweak interactions, we focus in this paper on the study of elastic scattering of a muon neutrinoExpand
Colloquium : Neutrino detectors as tools for nuclear security
In 1930, Wolfgang Pauli proposed that conservation of energy and momentum in beta decay required the existence of a new particle: the neutrino. Since then experimental methods have matured to theExpand
RADON REMOVAL FROM GASEOUS XENON FOR THE ENRICHED XENON OBSERVATORY
Neutrino oscillation experiments have shown definite evidence for non-zero neutrino masses. However, these experiments only tell us about neutrino mass differences, and nothing about the absoluteExpand

Implications of physics beyond the Standard Model in the quark and lepton sectors
The Standard Model (SM) of particle physics is a well-tested and predictive theory, being celebrated as one of the most successful models in newer time. However, non-zero neutrino masses, theExpand
