Particle physics: Can the gallium detector solve 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...

What can be learned with an iodine solar-neutrino detector?

We study the potential benefits of an iodine-based solar–neutrino detector for testing hypotheses that involve neutrino oscillations. We argue that such a detector will have a good chance of distinguishing the two allowed regions of ∆m – sin 2θ parameter space if neutrino conversion is occurring in the sun. It should also be able to detect seasonal variations in the signal due to vacuum oscilla...

Neutrino Physics Inside SK detector

The non-zero mass difference square of three generations of neutrino has already been verified in the K2K experiment conducted in Japan. But we still need more experimental data to have more accurate results about neutrinos. New generation of neutrino experiments are being built up in all over the world. Here I would like to present some Monte Carlo results using a special neutrino beam passing...
