Using Neutrinos to test the Time-Energy Uncertainty Relation in an Extreme Regime
Ramaswamy S. Raghavan, Djordje Minic, Tatsu Takeuchi +1
We discuss a direct test of the relation of time and energy in the very long-lived decay of tritium (H3) (meanlife τ~ 18 yrs) with the width Γ~ 10^{-24} eV [set by the time-energy…
New Physics with MeV Neutrino Sources Brighter than a Thousand Suns
Sanjib K. Agarwalla, R. S. Raghavan
Short baseline oscillations of neutrinos (nue and nuebar) due to active-sterile (a-s) mixing can be observed explicitly using MeV neutrino beams and existing/planned neutrino detec…
Why Neutrino Lines are Hypersharp
R. S. Raghavan
It was recently pointed out that mono-energetic neutrino lines from the 2-body decay of tritium (tau ~ 18-y) can be emitted, a significant fraction, with natural line width (~10-24…
Time-Energy Uncertainty in Neutrino Resonance: Quest for the Limit of Validity of Quantum Mechanics
R. S. Raghavan
The role of quantum mechanical time-energy uncertainty (TEU) is central in resonant neutrino (nue) reactions (3H to 3He to 3H) because of the unusual 18 y lifetime of 3H. The TEU e…
Hypersharp Resonant Capture of Neutrinos as a Laboratory Probe of the Planck Length
R. S. Raghavan
The 18.6 keV antineutrino line from 2-body decay of 3H in crystals can be emitted with natural width because of motional averaging by lattice vibrations despite the very long lifet…
Hypersharp Resonant Capture of Anti-Neutrinos
R. S. Raghavan
Recent ideas suggest that the 18.6 keV antineutrino (nuebar) line from 2-body decay of 3H in crystals is emitted with natural width, motionally narrowed by lattice vibrations as in…
