How Neutrinos Get Mass and What Other Things May Happen besides Oscillations
نویسنده
چکیده
Add 3 heavy singlet right-handed neutrinos to the minimal standard model: 1 νR for each νL. Then the operator of Eq. (3) is realized because each heavy νR is linked to νLφ 0 with a Yukawa coupling f ; and since νR is allowed to have a large Majorana mass MR, the famous seesaw realtionship mν = m 2 D/MR is obtained, where mD = f〈φ0〉. This mechanism dominates the literature and is usually implied when a particular pattern of neutrino mass and mixing is proposed.

Covariant treatment of flavour oscillations
We perform a covariant wavepacket analysis of neutrino oscillations taking into account the lifetime of the neutrino production process . We find that flavour oscillations in space are washed out when the neutrinos are produced from long lived resonances and what may be observed in appearance/disappearance experiments is a uniform conversion probability independent of distance. The lifetime of ...
متن کاملModels of Neutrino Mass and Mixing
There are two basic theoretical approaches to obtaining neutrino mass and mixing. In the minimalist approach, one adds just enough new stuff to the Minimal Standard Model to get mν 6= 0 and Uαi 6= 1. In the holistic approach, one uses a general framework or principle to enlarge the Minimal Standard Model such that, among other things, mν 6= 0 and Uαi 6= 1. In both cases, there are important sid...

متن کاملNearly Mass-Degenerate Majorana Neutrinos: Double Beta Decay and Neutrino Oscillations
Assuming equal tree-level Majorana masses for the standard-model neutrinos, either from the canonical seesaw mechanism or from a heavy scalar triplet, I discuss how their radiative splitting may be relevant to neutrinoless double beta decay and neutrino oscillations. • Talk given at the International Conference on Non-Accelerator New Physics, Dubna, Russia (June 28 July 3, 1999).
