Neutrino Masses and Mixing: Evidence and Implications
Measurements of various features of the fluxes of atmospheric and solar neutrinos have provided evidence for neutrino oscillations and therefore for neutrino masses and mixing. We review the phenomenology of neutrino oscillations in vacuum and in matter. We present the existing evidence from solar and atmospheric neutrinos as well as the results from laboratory searches, including the final sta...
متن کاملFlavor Mixing, Quark Masses, Neutrino Masses and Neutrino Oscillations
We discuss first the flavor mixing of the quarks, using the texture zero mass matrices. Then we study a similar model for the mass matrices of the leptons. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles and can predict the masses of the neutrinos. We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric...
متن کاملImplications of Quark-Lepton Symmetry for Neutrino Masses and Oscillations
We identify a plausible scenario based on quark-lepton symmetry which correlates long baseline oscillations with maximal mixing to sterile neutrinos. The implication for the Sudbury Neutrino Observatory (SNO) is that the neutral current signal will be found to suffer the same suppression from the Standard Solar Model prediction as obtains for the charged current signal. Flavor mixing among acti...
متن کاملStatus and implications of neutrino masses: a brief panorama
With the historic discovery of the Higgs boson our picture of particle physics would have been complete were it not for the neutrino sector and cosmology. I briefly discuss the role of neutrino masses and mixing upon gauge coupling unification, electroweak breaking and the flavor sector. Time is ripe for new discoveries such as leptonic CP violation, charged lepton flavor violation and neutrino...
متن کاملNeutrino Masses and Mixing∗
The investigation of neutrino properties is a very important problem of today’s neutrino physics. The key problem is the problem of neutrino masses. If neutrinos are massive, they can be mixed. If the total lepton number is conserved, massive neutrinos are Dirac particles. If the neutrino masses are generated by an interaction that does not conserve the total lepton number, neutrinos with defin...
