We show that in theories of generalised teleparallel gravity, whose Lagrangians are algebraic functions of the usual teleparallel Lagrangian, the action and the field equations are not invariant unde...

Lorentz invariance nonzero minimal uncertainty

The suspicion that the existence of a minimal uncertainty in position measurements violates Lorentz invariance seems unfounded. It is shown that the existence of such a nonzero minimal uncertainty in...

From the study of a sample of about 62.3 million well reconstructed K0 S ! + decays recorded by the KLOE detector at the DANE accelerator in Frascati, the lifetimes of K0

We show that a proper field theoretical treatment of mixed (Dirac) neutrinos leads to non-trivial dispersion relations for the flavor states. We analyze such a situation in the framework of the non-li...
