Lepton Mass Effects in Single Pion Production by Neutrinos

We reconsider the Feynman-Kislinger-Ravndal model applied to neutrino-excitation of baryon resonances. The effects of lepton mass are included, using the formalism of Kuzmin, Lyubushkin and Naumov. In addition we take account of the pion-pole contribution to the hadronic axial vector current. Application of this new formalism to the reaction νμ +p → μ+∆ at Eν ∼ 1 GeV gives a suppressed cross se...

Mass Matrix of Majorana Neutrinos

We present a massive Majorana neutrino model and see how it is constrained from the solar and atmospheric neutrino deficit experiments. This model incorporates the seesaw mechanism and Peccei-Quinn symmetry. Its consequence to the neutrinoless double beta decay is also discussed.

Neutrinos Have Mass – so What ?

In this brief review, I discuss the new physics unveiled by neutrino oscillation experiments over the past several years, and discuss several attempts at understanding the mechanism behind neutrino masses and lepton mixing. It is fair to say that, while significant theoretical progress has been made, we are yet to construct a coherent picture that naturally explains non-zero, yet tiny, neutrino...

A Mass Relation for Neutrinos

A generalization of the well-known Georgi-Jarlskog relation (mμ/mτ ) = 3 (ms/mb) to neutrinos is found in the context of SO(10). This new relation is (mνμ/mντ ) = 16 (mc/mt), which is consistent with present data, assuming the small-angle MSW solution to the solar neutrino problem.

Coherent Pion Production by Neutrinos

I concentrate in this article on the reaction coherent pion production by neutrinos incident on nuclei. A special effort is made in order to describe the approximations entering the calculation. I conclude that the reaction is well understood and with appropriate data for hadronic reactions it can be computed for low and high neutrino energies. Because of shortage of space I omitted the resonan...
