TeV Right-handed Neutrinos and the Flavor-symmetry-improved Seesaw Mechanism [PDF]

, 1996
Horizontal flavor symmetries can drastically suppress Dirac neutrino masses well below those of the corresponding charged leptons. We show that models can be constructed where the light neutrino mass eigenvalues are small enough to give the MSW solution ...

Zenith angle distributions at Super-Kamiokande and SNO and the solution of the solar neutrino problem [PDF]

, 2000
We have performed a detailed study of the zenith angle dependence of the regeneration factor and distributions of events at SNO and SK for different solutions of the solar neutrino problem.

Approximate Flavor Symmetries in the Lepton Sector [PDF]

, 1993
Approximate flavor symmetries in the quark sector have been used as a handle on physics beyond the Standard Model. Due to the great interest in neutrino masses and mixings and the wealth of existing and proposed neutrino experiments it is important to ...

Solving the Solar Neutrino Problem

Journal of High Energy Physics, Gravitation and Cosmology, 2021
A new theoretical prediction that a plasma can produce antineutrinos is used to solve the solar neutrino problem. The difference between electron-positron induced fusion, and inertial fusion experiments that have been unsuccessful so far as commercial fusion reactors is also discussed.

SN 1987A and the status of oscillation solutions to the solar neutrino problem [PDF]

, 2001
We study neutrino oscillations and the level-crossing probability ${P}_{\mathrm{LSZ}}$ in power-law potential profiles $A(r)\ensuremath{\propto}{r}^{n}.$ We give local and global adiabaticity conditions valid for all mixing angles $\ensuremath{\vartheta}$

Constraining neutrino oscillation parameters with current solar and atmospheric data [PDF]

, 2003
We analyze the impact of recent solar, atmospheric and reactor data in the determination of the neutrino oscillation parameters, taking into account that both the solar nu_e and the atmospheric nu_mu may convert to a mixture of active and sterile ...

A 4-neutrino model with a Higgs triplet [PDF]

, 1999
We take as a starting point the Gelmini -- Roncadelli model enlarged by a term with explicit lepton number violation in the Higgs potential and add a neutrino singlet field coupled via a scalar doublet to the usual leptons.

Neutrino Oscillations and the Solar Neutrino Problem [PDF]

, 2001
I describe the current status of the solar neutrino problem, summarizing the arguments that its resolution will require new particle physics. The phenomenon of matter-enhanced neutrino oscillations is reviewed. I consider the implications of current experiments -- including the SuperKamiokande atmospheric and LSND measurements -- and the need for ...

$ ^7 Be$ Neutrino Signal Variation in KamLAND

, 2005
Large Mixing Angle (LMA) neutrino oscillation is the main solution for the long-standing Solar Neutrino Problem (SNP). Whether there is any subdominant effect accompanying the dominant LMA solution can not be ruled out at the moment, but will be settled ...
