Interplay of Non-Relativistic and Relativistic Effects in Neutrino Oscillations

A theoretical structure that involves neutrino mass eigenstates at non relativistic as well as relativistic energies is presented. Using this framework, we find that if the particle X, with mass 33.9 MeV, of the KARMEN collaboration anomaly is identified with the third neutrino mass eigenstate, then the present limit of 23 MeV upper bound on the tau neutrino mass implies |Uτ3| < 0.82. Typeset u...

New Limits on Tau Neutrino Mass from CLEO II

I report on two studies of tau neutrino mass recently carried out using data collected with the CLEO II detector at the CESR ee collider. First I present the results of an analysis of 473 decays of the type ! 5 and ! 3 2 , from which a 95% CL upper limit on m of 30 MeV is obtained. Results are also presented from a preliminary analysis of the decay ! 3 , using a sample of 29; 000 reconstructed ...

2 v 1 2 9 M ar 1 99 8 On mixing angles and magnetic moment of heavy tau

If the magnetic moment of unstable tau neutrinos with the mass of O(MeV) is in the region of 10 −8 µ B µ ντ 10 −6 µ B , it is compatible with the present experimental and cosmological bounds. It is pointed out here, that if the tau neutrino has such a large magnetic moment and can oscillate into a neutrino of another flavour the results from νe scattering experiment at LAMPF constrain the tau n...

An improved cosmological bound on the tau-neutrino mass

We consider the influence of non-equilibrium electronic neutrinos (and anti-neutrinos) on the neutron-to-proton ratio. These neutrinos would come from massive ντ annihilations ν̄τντ → ν̄eνe. For sufficiently large ντ masses this new effect would strongly enhance the (n/p)-ratio, leading to a very stringent bound on the ντ mass, even adopting a rather weak upper bound on the effective number on ne...

CLNS 00/1714 A Biased Review of Tau Neutrino Mass Limits

After a quick review of astrophysically relevant limits, I present a summary of MeV scale tau neutrino mass limits derived from accelerator based experiments. I argue that the current published limits appear to be too consistent, and that we therefore cannot conclude that the tau neutrino mass limit is as low as usually claimed. I provide motivational arguments calling into question the assumed...

Limits on ν μ → ν τ oscillations and tau neutrino magnetic moment from muon neutrino - electron scattering

Limits on ν µ → ν τ oscillations and tau neutrino magnetic moment from muon neutrino-electron scattering Abstract If the tau neutrino has large magnetic moment it might be effectively used to search for ν µ − ν τ neutrino oscillations in muon neutrino-electron scattering in beam dump experiments. Using the present experimental limits on the magnetic moments of tau and muon neutrinos as correspo...
