New answer to the solar neutrino problem

The Solar Neutrino Problem

Neutrino oscillations and the solar-neutrino problem.

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 neutrino and LSND measurements – and the need for additional constraints from SNO and other...

Fcnc Solutions to the Solar Neutrino Problem

In his seminal paper 1 Lincoln Wolfenstein considered flavor changing neutral current (FCNC) effects on neutrino oscillations. He noticed that if the neutrino current in the effective four-fermion interaction Lagrangian has a flavor nonsymmetric part it can significantly affect neutrino oscillations by changing the neutrino indices of refraction in matter. Furthermore, if the neutrinos are mass...

Maximal neutrino oscillation solution to the solar neutrino problem

We discuss a simple predictive solution to the solar neutrino problem based on maximal vacuum neutrino oscillations. The solution can be motivated by the exact parity symmetric model which predicts that the neutrino mass eigenstates are maximal mixtures of ordinary and mirror weak eigen-states (if neutrinos are massive). We show that this proposed solution to the solar neutrino problem is in re...
