Renormalizable and unitary nonlocal quantum field theory with CPT violation and its implication
Moshe M. Chaichian, Markku A. Oksanen, Anca Tureanu
It is a common belief that any relativistic nonlocal quantum field theory encounters either the problem of renormalizability or unitarity or both of them. It is also known that any…
On Massive Neutrinos and Coherence in Neutrino Oscillations
Anca Tureanu
We examine the central tenet of the current standard theory of neutrino oscillations, namely the assumption that neutrinos are emitted and detected as flavour neutrino states, whic…
Below the Schwinger critical magnetic field value, quantum vacuum and gamma-ray bursts delay
Iver H. Brevik, Moshe M. Chaichian, Anca Tureanu
A magnetic field above the Schwinger critical value Tesla is much higher than any magnetic field known by now in the interstellar bulk except in the vicinity…
Note on a BCS analogy of Majorana neutrinos
Kazuo Fujikawa, Anca Tureanu
In this note, we discuss an analogy between the BCS theory and the seesaw model of neutrinos. We believe that the analogy indicates some fundamental aspects of Majorana neutrinos.…
Neutrino Flavour Waves Through the Quantum Vacuum: A Theory of Oscillations
Markku Oksanen, Nico Stirling, Anca Tureanu
We propose a theory for neutrino oscillations, in which the flavour neutrinos are treated as waves of massless particles propagating in a "refractive quantum vacuum" and obeying a…
