On the group velocity of oscillating neutrino states and the equal velocity assumption
J. -M. Levy
In a two flavour world, the usual equal , equal , or equal assumptions used to derive the neutrino oscillation length can be replaced by a specific definition of the velo…

On the derivation of the neutrino oscillation length formula
Jean-Michel Levy
Forsaking the traditionnal hand-waving in the treatment of the motion, we show that the ultra-relativistic approximation and the equality of kinematical variables are unnecessary i…

A consistent interpretation of the Karmen anomaly
J. -M. Levy, F. Vannucci
The Karmen anomaly can be interpreted as being due to a heavy neutrino of mass around 137 MeV produced in decays. This interpretation is consistent with the present limit…
